Before some time i coded my own little db editor program, i was coding it from the zero using Win API's so its not very small project. It was working fine on all OS till now, i have Win 7 x64 with all latest updates and my application is crashing with 0xC000005 exception because of some of the Heap functions(HeapAlloc or HeapFree, i use nothing else), i tried replacing HeapAlloc & HeapFree with VirtualAlloc and VirtualFree and it was all fine, but i dont want to use the virtual memory.... Something else, i tried to attach with debugger to trace the problem, but when i attach debugger its not crashing, then i tried to display MessageBox to trace where it crashes, but when i display MessageBox its not crashing too....
My application is running as 32bit process. Coded in C.
Anyone had similar problem ?
