[Octave-bug-tracker] [bug #41699] imformats causes a segmentation fault on Windows when Octave exits

[Rik]

Follow-up Comment #84, bug #41699 (project octave):

Alas, the problem still remains.  I checked the config.log for graphicsmagick
and it is being built with -fopenmp.  I also have OMP_NUM_THREADS set to 1.

I ran octave-cli.exe under gdb and got a backtrace.  It's not tremendously
helpful because the debugging symbols were stripped.  Still, it appears that
we vector through the Fsylvester at #8.  That's really odd.


Program received signal SIGSEGV, Segmentation fault.
