	i am running in a strange segfault with loading an #include'd text file with a large 2dim array. first i create the array with giSnippets[][] init 767, 6 then i fill this array with lines like giSnippets fillarray 1, 0.697, 3.850, 66.20, -38.8, 0.77, 2, 2.125, 3.840, 89.43, -26.8, 0.43 etc this used to run fine the last days, but crashes now constantly. i tried to break this down, and found that commenting out one more item (in the example: putting the /* after 334) does not crash any more. the strange thing is that "it worked yesterday" and i haven't compiled csound since then. so i assume that it is a memory leak? the terminal output is below; perhaps it gives a clue to someone. best - joachim jh@lenov2:/media/jh/Daten/Joachim/Stuecke/49_quantum/csd$ csound 190104_c_problem.csd

	This part (line 2340) is not quite my code, although I might have touched it to adjust or fix things. The allocation of memory is, in the case of arrays, only concerned with ARRAYDAT structure, the actual memory for the data is allocate by code in array.c. The memory allocated includes all the space for variables in the instrument as provided by INSTRTXT. The amount required is defined by the compiler code. The loop starting at 2487 connects opcode arguments with their sources (pointers). Line 2491 is the case for constants. I did not write this code originally, but I might have fixed bits while we were working on 6.0. I would have expected that the list is correctly NULL terminated and the compiler would have provided a correct number of arguments. Not sure what the issue is.

	I looked at Joachim’s code, and I am still puzzled as to how the number of arguments to fillarray is limited. Is there a limit? What’s the limit? The insert.c code surely does not expect a hard limit in terms of inargs. If there is one, then we can place a check somewhere (but not here, it needs to be a compile/parse/syntax error). ======================= Prof. Victor Lazzarini Dean of Arts, Celtic Studies, and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 > On 4 Jan 2019, at 16:28, jpff wrote: > > As I thought > > graphics suppressed, ascii substituted > 0dBFS level = 1.0 > ==4383== Invalid write of size 8 > ==4383== at 0x4E992E4: instance (insert.c:2491) > ==4383== by 0x4E9A319: init0 (insert.c:235) > ==4383== by 0x4EA4E1D: musmon (musmon.c:254) > ==4383== by 0x4FF0DE1: csoundStart (main.c:498) > ==4383== by 0x4013CF: main (csound_main.c:324) > ==4383== Address 0x1ba291f8 is 0 bytes after a block of size 32,536 alloc'd > ==4383== at 0x4C30035: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) > ==4383== by 0x4EA1B62: mcalloc (memalloc.c:113) > ==4383== by 0x4E98F7C: instance (insert.c:2340) > ==4383== by 0x4E9A319: init0 (insert.c:235) > ==4383== by 0x4EA4E1D: musmon (musmon.c:254) > ==4383== by 0x4FF0DE1: csoundStart (main.c:498) > ==4383== by 0x4013CF: main (csound_main.c:324) > > etc > > > Mainly Victor's code.

It creates the 2D array as I would expect and has the correct sizes etc. In the loop to copy the values (arrays.c lines 265-169) in fillbuf all looks good to start with but at sime stage unsecified the src address becomes totally wrong, anf d not a valifd pointerat all.

I attached a csd that goes in crash. --- Mauro Il 2019-01-04 18:39 Victor Lazzarini ha scritto: I looked at Joachim's code, and I am still puzzled as to how the number of arguments to fillarray is limited. Is there a limit? What's the limit? The insert.c code surely does not expect a hard limit in terms of inargs. If there is one, then we can place a check somewhere (but not here, it needs to be a compile/parse/syntax error). ======================= Prof. Victor Lazzarini Dean of Arts, Celtic Studies, and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 On 4 Jan 2019, at 16:28, jpff <jpff@codemist.co.uk> wrote: As I thought graphics suppressed, ascii substituted 0dBFS level = 1.0 ==4383== Invalid write of size 8 ==4383== at 0x4E992E4: instance (insert.c:2491) ==4383== by 0x4E9A319: init0 (insert.c:235) ==4383== by 0x4EA4E1D: musmon (musmon.c:254) ==4383== by 0x4FF0DE1: csoundStart (main.c:498) ==4383== by 0x4013CF: main (csound_main.c:324) ==4383== Address 0x1ba291f8 is 0 bytes after a block of size 32,536 alloc'd ==4383== at 0x4C30035: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==4383== by 0x4EA1B62: mcalloc (memalloc.c:113) ==4383== by 0x4E98F7C: instance (insert.c:2340) ==4383== by 0x4E9A319: init0 (insert.c:235) ==4383== by 0x4EA4E1D: musmon (musmon.c:254) ==4383== by 0x4FF0DE1: csoundStart (main.c:498) ==4383== by 0x4013CF: main (csound_main.c:324) etc Mainly Victor's code. I see no check that the number of arguments is limited. The allocation includes many things (line 2340) and it iruns a loop on i with no limit just a list of args. ==J

	Same problem. There is a fixed size array of 1999 values in fillarray and ftgen with no check.

	So, the problem is here? in H/csoundCore.h: #define VARGMAX (1999) If I understand correctly, it means that, for each opcode inside a csd code, Csound always reserves an array of 1999 pointers for its args (~16KB for each opcode if we consider 64bit pointers). It would be nice if Csound could reserve memory just for the number of args each specific opcode needs. In this way, that limit of VARGMAX should not be needed anymore, but I suppose it's not an easy task and it would require changing a big amount of source code... Another way could be to allow "join" of arrays or ftables. In this way, we could just define a table splitted in many arrays and then join them with another opcode. Something like: iArr1 fillarray 1, 2, ..., 1993 iArr2 fillarray 1994, ..., 3986 iArr2 fillarray 3987, ..., 5979 iArr joinarray iArr1, iArr2, iArr3 This should allow the user to overcome that args limit by simply adding a new opcode to join arrays and another one to make the same thing with ftables. What do you think? --- Mauro Il 2019-01-04 22:11 jpff ha scritto: Same problem. There is a fixed size array of 1999 values in fillarray and ftgen with no check. If he gen02 is in the score than that is different and a bug.

	Sorry, I should've used the brackets in my previous example: iArr1[] fillarray 1, 2, ..., 1993 iArr2[] fillarray 1994, ..., 3986 iArr3[] fillarray 3987, ..., 5979 iArr[] joinarray iArr1, iArr2, iArr3 And being that, once joined, probably I don't need anymore the splitted arrays, it could be nice if I could tell Csound to "free" memory for those. I suppose this could already be done with "iArr init 1" ? Anyway, when there is an opcode with more than 1999 args, it would be nice if Csound would stop the parsing and tell the user that he can't use more than VARGMAX number of args, instead of crashing. --- Mauro Il 2019-01-05 11:10 Mauro Giubileo ha scritto: So, the problem is here? in H/csoundCore.h: #define VARGMAX (1999) If I understand correctly, it means that, for each opcode inside a csd code, Csound always reserves an array of 1999 pointers for its args (~16KB for each opcode if we consider 64bit pointers).
