SegFault in __mingwthr_run_key_dtors.part.0 () ()

my code crashes when I close the program, and it give the following error when I run the debugger. I'm using C++ in conde::blocks with the MingW/GCC++ compiler. I'm new to debugging so I don't really know how to approach this as the compiler doesn't point to a specific line in the code. Or at least my code that is.
