[Octave-bug-tracker] [bug #44420] Memory leaks in 4.0 RC

[Robert Jenssen]

Follow-up Comment #8, bug #44420 (project octave):

I've looked around a bit more and I think I understand things a little better.
Sorry for the noise. I found the comment in toplev.cc about "Don't call
singleton_cleanup_list ..." and uncommented the cleanup call and
commented the typeinfo cleanup call:

Now "cdef_manager::cleanup_instance()" gets called.
