Do you get an error when starting a SFML project?

Question

When I run the project in Release I get this error. In debug everything works fine.

Answer 1

Looks like some sort of memory bug.
You are doing something wrong somewhere: either you are crawling out of the array boundaries, or you are doing use after free, or some other mistake.
If your code is not large, then bring it (in code tags!).
