Is there a way to increase the size of the stack given to fgfs in Mac OS X? I heard of a ulimit command but my machine (10.2.4) doesn't seem to have this. Unsure if stack growing into the heap or vice versa is the problem here.
This is a modified version of flightgear of a friend with a mixture of C++ and C pointer manipulation.
Any suggestions on how to begin debugging this? They're currently doing the cout/asm ("trap") route. The problem seems specific to memory allocation, some local (stack), some via new. He swears that he isn't deleting anything twice. Problem usually occurs soon after the procedure is called and returns (in a call or object allocation immediately following this proc). The pointer work steps through a buffer got from handleBufferRead() (netBufferChannel)
I want to stress again the problem is not in cvs code. With the changes commented out, fg comes up fine.
Thanks,
Ima
