[Octave-bug-tracker] [bug #36067] bug in exist() when checking for a faulty mex/oct file

[Mike Miller]

Update of bug #36067 (project octave):

                  Status:            Works For Me => Confirmed              
                 Release:                   3.6.1 => dev

Follow-up Comment #9:

Thanks for the new test case, segfault confirmed with this one on the dev
branch. Yes, Octave is trying to load the named mex/oct file into the symbol
table if the name matches.

Your suggestion about bypassing the symbol table lookup if an extension was
given may be worth pursuing. I think the entire block that handles the symbol
table search results will fall through if the given string looks like it has a
file extension.

So to be clear, are you looking for a fix to avoid a crash when a string is
given that happens to have the same base name as a buggy mex/oct function,
exist ("causesegfault.bla"), or even exist ("causesegfault.oct"), but you
don't have a problem with a crash on exist ("causesegfault")?
