The Lua opcodes are giving me that warning, because dsblksiz is uint16 (max 65535), but sizeof(lua_opcall) and sizeof(lua_opcall_off) are 98368 on my machine.
The large size seems to be the fault of a 0x3000 sized array of pointers, which in a 64bit machine yields 0x3000 * 8 = 98304. 32bit may be spared of the problem, since pointer size is 4 bytes instead of 8.
It seems to me that 12288 arguments is a bit overkill. Can the size be reduced? 0x300 should be enough for everybody (tm) and eliminate this problem. Saludos, Felipe Sateler |

I will fix this, thanks for the bug report. Regards, Mike On Sat, Mar 2, 2013 at 8:11 AM, Felipe Sateler <fsateler@gmail.com> wrote:

I have fixed this now in both 5 and 6. The size is now 1000 (decimal) pointers to MYFLT. Thanks again, Mike

BTW, csound6 CsoundAC is failing to build for me. frontends/CsoundAC/ChordSpace.hpp:3536:24: error: ‘R’ was not declared in this scope

You need to enable c++11 for that. R denotes a multi-line string constant introduced in c++11. Regards, Mike

OK, probably needs to be tested for and enabled for CsoundAC. UNfortunately gcc supports c++11 only from 4.7 onwards. Or is this supported in c++0x?

Also, c++11 seems to break abi compatibility in gcc: On Sat, Mar 2, 2013 at 3:59 PM, Felipe Sateler <fsateler@gmail.com> wrote:

It began to be supported along the way somewhere in c++0x, not sure just when. But I believe before 4.7. Regards, Mike

I see that. I use std throughout my code. I think if you enable c++0x for everything that includes the C++ standard library it should be OK. Or we could enable it for all C++. This of course is what I do when I build it. Regards, Mike On Sat, Mar 2, 2013 at 2:13 PM, Michael Gogins <michael.gogins@gmail.com> wrote:
