This may be due to the fact that I have a different CPU from yours: OpenBLAS has a different kernel for each microarchitecture, and the bug you encountered is probably specific to yours. Here are a few inquiries: - if you have access to a Debian unstable system on the same hardware, are you still able to replicate the bug? Debian unstable has a more recent version of OpenBLAS (0.2.19), which may already contain a bugfix. If you don't have a Debian unstable system, you can create one inside a chroot (see https://wiki.debian.org/chroot for some explanations) - I need to know which OpenBLAS kernel you are using. The easiest way of figuring it is to install the "julia" package, then run "julia" at the shell prompt, and then type "versioninfo()" at the julia prompt. Then copy/paste the output - is it possible to have a backtrace of the crash? Please install the octave-dbg package (unfortunately there is no debug package for OpenBLAS in Debian jessie). Then run octave from gdb, and get a backtrace. See https://wiki.debian.org/HowToGetABacktrace for more details (note: the part on automatic debug packages only applies to Debian unstable, not to Debian jessie) Best, -- .''`.
