If you can compile your own version of Crafty, can you please make the following
experiment: in file utility.c search for "WinFreeInterleaved", and replace
void WinFreeInterleaved(void *pMemory, size_t cBytes) {
VirtualFree(pMemory, // base address of block
cBytes, // bytes of committed pages
MEM_DECOMMIT|MEM_RELEASE); // decommit the pages
}
by
void WinFreeInterleaved(void *pMemory, size_t cBytes) {
VirtualFree(pMemory, 0, MEM_RELEASE);
}
I suspect that will fix the problem.
Thanks,
Eugene
