Getting 'std::bad_alloc' is almost guaranteed to be caused by either
heap corruption, or using uninitialized value while new()ing of
malloc()ing memory.

While allocating your arrays on the stack may make the bug hide,
it will not fix it.

Rebuild your program in debug mode and check it with valgrind,
you'll almost certainly find at least one bug in it.
