[Octave-bug-tracker] [bug #35661] GNU Octave 3.6.0 crashed in surf()

[John W. Eaton]

Follow-up Comment #4, bug #35661 (project octave):

OK, I see the problem now.  I unpacked with uzip -a and it treated the .mat
file as a text file...

I see the error about texturemap but I'm not seeing a segfault, even after
removing the try/catch.  However, valgrind does turn up this:
