I also tried to run my program under windbg. With my first run (command GN twice), I could see my program running and then stop with the same kind of error (STATUS_ACCESS_VIOLATION). However, I don't understand anything of what windbg told me : 0:000> KP 20 Child-SP          RetAddr           Call Site 00000000`0008e318 00000000`74b8601a ntdll!NtTerminateProcess+0xa 00000000`0008e320 00000000`74b7cf87 wow64!Wow64EmulateAtlThunk+0x86ba 00000000`0008e350 00000000`74b02776 wow64!Wow64SystemServiceEx+0xd7 00000000`0008ec10 00000000`74b7d07e wow64cpu!TurboDispatchJumpAddressEnd+0x2d 00000000`0008ecd0 00000000`74b7c549 wow64!Wow64SystemServiceEx+0x1ce 00000000`0008ed20 00000000`77384956 wow64!Wow64LdrpInitialize+0x429 00000000`0008f270 00000000`77381a17 ntdll!RtlUniform+0x6e6 00000000`0008f760 00000000`7736c32e ntdll!RtlCreateTagHeap+0xa7 00000000`0008f7d0 00000000`00000000 ntdll!LdrInitializeThunk+0xe 0:000> As I'm clearly not even a usual user, this is completely unknown for me.
