Yes, I also had a hard time to find this out. I added a lot of debug
statements in destructors to see when the first occurrence of the
double free happened exactly. ASAN was a big help, but finally you
need to understand what he was doing. I was surprised that he didn't
include pointers in the objects but used the linked list

... as separate objects. But I didn't pursue this further, I just wanted
to fix the bug, be it in Cartesian or FLTK.
I'm glad that this fixes the issue for you, thanks for confirmation.
