In that case what you should do is to take the code where the problem
happens and start removing small parts of it, checking every time if
the problem still happens. If at some point the problem disappears
you may have found the problematic code. If that still doesn't help
understanding what's going on, continue removing other parts of the
code until you can't remove anything without making the problem
disappear. Anything that doesn't affect the problem, remove, until
you have the minimal amount of code that still exhibits the problem.

We don't need any makefile. Just C++ code ought to be enough.
(At most you could tell which compiler and compiler options you are
using.)
