VS console vs. GUI discrepensies

[jetimms]

I have a console program that I am running that causes a crash ran from the console version, but in the VSC++ IDE (using Debug), it raises no errors.

What are some reasons this can happen?

Thanks.

The debug heap is different from the release heap, it has header/trailer blocks around each allocation and checking facilities. This will change the application behaviour in the presence of an errant pointer.
