It is difficult to diagnose without seeing your code or a small compilable
example that illustrates the problem.
Usually if a program runs differently in debug and release there are
uninitialized variables. Another possibility is accessing invalid memory or
memory that is corrupted by the program. If you have access to a linux
system, you could try running valgrind to find the source of the error.
