FLTK has no negative interaction with malloc or fraed or similar.
I highly recommend using a debugger to find out what exactly causes the
crash. Working efficiently with a debugger needs some training but will save
you hours and days of blind guessing.
Even if code worked for years, a slight change may trigger some buffer
overrun that once was harmless but now causes a crash. Just because a
function runs to the end does not mean that it won't cause a crash later in
the code.
If you are on Linux, and gdb does not solve the issue because there is some
random corrupt memory, then "Valgrind" is the perfect tool for you.
