have you looked at the backtrace of the crash [1] or used Valgrind to
check if you're causing some kind of memory corruption [2] ? In my
experience, these are the two most helpful things you can do when
facing any kind of mysterious crash.
Best regards,

[1] gdb <name of executable>
At gdb prompt, type r <Enter>, wait for crash, type bt <enter>
That tells you where exactly the crash occurs.
[2] valgrind <name of executable>
(note that this will slow down your program considerably)
