[Octave-bug-tracker] [bug #64620] Nested functions handles make stack frames leak

[Petter T.]

Follow-up Comment #1, bug #64620 (project octave):


Nested functions handles make stack frames leak (bug #64620)

If the handle is saved on parent frames.

* libinterp/corefcn/call-stack.cc: Clear static and parent link on frame pop
* libinterp/corefcn/stack-frame.h: Mark closure for all linked accesses.
                                   Fn to clear parent and static link.
* libinterp/octave-value/ov-fcn-handle.cc: Search access links for context
frame match
* test/bug-64620/: Tests


I was able to run of of memory by doing:

while true
  bug_64620_1;
end


,from the CLI (top scope).
