[Octave-bug-tracker] [bug #61472] AddressSanitizer crash in MEX tests

[Markus Mützel]

Follow-up Comment #16, bug #61472 (project octave):

Your change e38202d3628d seems to have greatly reduced the number of warnings
on the macOS runners about "direct access to global weak symbols" (see bug
#59820). The remaining ones are mostly about instantiations involving `class
Sparse<T>` and `class octave_int<T>` templates afaict.
Maybe if we take the same approach (dedicated headers to provide guarded
forward declarations for those template classes), we could reduce the impact
of that bug. Maybe that could also resolve the issue you are seeing when using
the patches you provided here with enabled visibility flags.
