Hi all I saw this thread when searching for a similar error I'm getting. Mine is not with large binaries, but with lots of memory allocations (I'm doing some processing on a large IC netlist). When my program reaches around 800 MB of memory or so it will crash. I tried to use GDB but it just gave me code C0000005 and nothing to locate the problem. I tried to catch a failed memory allocation using a std::bad_alloc exception but it doesn't seem to get thrown.
I'm using cygwin 1007.5.0 on Vista 32-bit Enterprise... Any ideas about this?
