Follow-up Comment #18, bug #36067 (project octave):
One possibility to reduce the severity of problems with segfaults in mex/oct
files is to make the SIGSEGV handler throw and exception, and surround calls
to the mex file by try/catch.
If an exception is caught, then a useful error message could be printed saying
which mex file was to blame, and possibly giving the user the opportunity to
debug a little. It should warn the user that the system has become unstable
and should be restarted soon.
The same could be applied to known bugs with other libraries, like the
graphics drivers.
