Follow-up Comment #15, bug #59228 (project octave):

I applied your patch to the stable branch here
(http://hg.savannah.gnu.org/hgweb/octave/rev/d4d8c004457f) and then merged
with default.  I've been checking in a lot of code lately and haven't been
keeping up with the QA (quality assurance).

It's a shame that the segfault issues are not completely resolved.  It may
mean that there are still instances in Octave where variables are being freed
from the stack.  I'm adding Markus to the CC list since he might know the
answer.

@Markus: is there an automated way to detect incorrect freeing of variables on
the stack?  Were you working from a static analysis of the code?
