Debug assertion failure???

[LanyA]

Hello again - does anyone understand what a debug assertion failure is? I am running my exe from DOS, and i get this dialog box with this message 20% of the time:

Debug Assertion Failed!

Program: C:\Program Files\MPRCrypto\mprcrypto.exe
File: dbgheap.c
Line: 1017

Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts.

What's this? And how could I prevent this? Anyone?

You probably write beyond some allocated block of memory.

When you hit the assert in debug... debug the code. Look at the call stack and follow it back to see where it is coming from.
