Subject	[Cs-dev] memory issue on OSX (strings)
	Hi all, Backstory here: https://github.com/csound/csound/issues/506 I'm trying to figure out some memory issues that I'm having with a complex csd (reposting this problem here as I'm unsure how many people look at github). The short version of the story is that the seg faults are intermittent and, when I remove references to soundfiles on my machine, they seem to magically disappear, making it difficult to post a demonstrative csd. This bug almost certainly has to do with strings, but I've been struggling to make a csd that yall can run without my soundfile database. However I've finally gotten a file-independent csd that doesn't seg fault, but throws valgrind memory errors for me (on OSX 10.9): http://pastebin.com/tHMe15Li If anyone has any insight regarding this is would be much appreciated, as similar, more complex scores are failing to compile for me at this point.

	This pastebin is file-independant. The filenames in the score are not actually used for anything and it should run on any machine (unlike the one I originally posted).

	This latest pastebin seems to have different behavior than the others. I'm getting a crash in deact, deactivating what looks like an infinite loop in a UDO. I'm not really sure what the cause of that is. Reverting the fix I put in for labels and gotos (https://github.com/csound/csound/commit/24b7e94d1bb5c35e39565bb735f4c6bf81b1aea5) that Stephane pointed out in the github issue does make the deact crash go away. I got valgrind installed here and with the original pastebin example I get a few intermittent errors but trying out various code changes doesn't seem to affect the results.

	Thanks for the followup Steven. I’m not particularly bothered by the valgrind errors, but in larger csds with lots of file reads things start crashing reliably for me. Attached is a csd which consistently segfaults for me (after deact) with the 5.06 release code. Should work on any machine.

	I've reverted the change I had introduced originally. This fixes the regressions introduced but reintroduces the problem of labels as the things in UDO's causing jumps to fail. Seems the lesser of two evils. The original bug has to do with code like this: opcode Loop,k,kk kend,kcnt xin until kcnt > kend do kcnt += 1 od xout kcnt endop Which failed to process the until loop (which compiles to a label and goto). Ben: Your latest CSD fails here but again in different ways from before. In this case, i'm testing with the latest after I commited the reverted code. It's still crashing, but for a different reason. First, I found that the code you had assigning p3 directly from xin was causing a problem. I'm not sure from Csound's UDO design that it ever worked to allow this. Changing the code to swap out idur for p3 in those UDO's, then adding a "p3 = idur" seems to have gotten around that one. After that, there's still a crash having to do with chnget. Somehow a bad entry has gotten into the channel hash table. I'm not sure what's the story with that though. I've got to take a break from this. Hopefully someone else can take a look too.

	Dear Steven, First, I found that the code you had assigning p3 directly from xin was causing a problem. That was silly! Thanks for spotting that, I’ve sorted it out. The problem with the chnget/set hash table must be the issue that is causing my problems. I’ve never used the chn* opcodes until recently; I’ve been using those (poorly written) opcodes with p3 in xin for years. Thanks for your time.

	Hi Brian, If the p3 assignment in xin worked previously, then I suppose we could address it as a regression. However, I think personally I'd rather treat it as unspecified behavior and a bug. I guess we could put up a vote or something? For channels, I guess we're moving forward and that's the next step to investigate.

	Dear Steven, If the p3 assignment in xin worked previously, then I suppose we could address it as a regression. However, I think personally I'd rather treat it as unspecified behavior and a bug. I guess we could put up a vote or something? No, I agree that this shouldn’t be supported behaviour. For channels, I guess we're moving forward and that's the next step to investigate. Does anyone have any input on the channel hash table bug?

That was silly! Thanks for spotting that, I’ve sorted it out. The problem with the chnget/set hash table must be the issue that is causing my problems. I’ve never used the chn* opcodes until recently; I’ve been using those (poorly written) opcodes with p3 in xin for years. Thanks for your time.

This fixes the regressions introduced but reintroduces the problem of labels as the things in UDO's causing jumps to fail. Seems the lesser of two evils. The original bug has to do with code like this: opcode Loop,k,kk kend,kcnt xin until kcnt > kend do kcnt += 1 od xout kcnt endop Which failed to process the until loop (which compiles to a label and goto). Ben: Your latest CSD fails here but again in different ways from before. In this case, i'm testing with the latest after I commited the reverted code. It's still crashing, but for a different reason. First, I found that the code you had assigning p3 directly from xin was causing a problem. I'm not sure from Csound's UDO design that it ever worked to allow this. Changing the code to swap out idur for p3 in those UDO's, then adding a "p3 = idur" seems to have gotten around that one. After that, there's still a crash having to do with chnget. Somehow a bad entry has gotten into the channel hash table. I'm not sure what's the story with that though. I've got to take a break from this. Hopefully someone else can take a look too.

I'm getting a crash in deact, deactivating what looks like an infinite loop in a UDO. I'm not really sure what the cause of that is. Reverting the fix I put in for labels and gotos (https://github.com/csound/csound/commit/24b7e94d1bb5c35e39565bb735f4c6bf81b1aea5) that Stephane pointed out in the github issue does make the deact crash go away. I got valgrind installed here and with the original pastebin example I get a few intermittent errors but trying out various code changes doesn't seem to affect the results. Reverting the commit mentioned above does not seem to affect the valgrind errors.
