Follow-up Comment #18, bug #47914 (project octave):
Hi,
I'm a random octave user, and I am finding this in my own C++ applications
when compiled with ubsan. I have the same backtrace (different symbol
position, but same ubsan error and stack depth).
I found this bug when searching for the crash message - perhaps this is indeed
a problem with the video driver...
I'm using debian testing (x86_64), octave 4.0.3-1, as a virtualbox guest
(4.3.30 r101610).
I've fired off a rebuild of the octave package with ubsan enabled, but it
looks like it might take a while - I'll get back when I have a test package.
