[Octave-bug-tracker] [bug #65547] Byte-code machine working in debug mode causes crash / core dump

[Petter]

Follow-up Comment #2, bug #65547 (group octave):

It seems like the catch of any quit_debug_exception need to happen at a lot
more places, when unwinding multiple stack frames, than added in
https://savannah.gnu.org/bugs/?65056

I've made an patch that seems to address the issue. I can't recreate the
problem after applying the patch.


Catch debug exit exceptions in nested bytecode contexts (bug #65547)

When debugging is aborted, and there are nested bytecode interpreters,
the exit debug exception would not be handled properly.

Also, add some missed handling of exit exceptions.

* pt-bytecode-vm-internal.h: Add CATCH_DEBUG_EXCEPTION macro def.
                             Wrap tries with the macro.
                             Add missing CATCH_EXIT_EXCEPTION.
* pt-bytecode-vm.cc: Wrap tries with the CATCH_DEBUG_EXCEPTION macro


(file #55918)
