Bug#794443: [Pkg-octave-devel] Bug#794443: octave: should notrecommendlibopenblas-base
Dear maintainers, I'm sorry that in my system Debian stable (jessie) there is no package libopenblas-dbg, so I could not do the backtrace. Besides, after octave 4.0 came into jessie-backports I had upgrade my octave package from 3.8 to 4.0 (currently version is octave 4.0.2-1~bpo8+1), and in this new version this crash bug no longer exists. Thanks maintainers.

A backtrace would be useful. Please do the following: - install the following packages: gdb, octave-dbg, libopenblas-dbg - run octave from gdb (with "gdb octave-cli"), then type "run" at the gdb prompt. You should get the octave prompt - from the octave prompt, trigger the crash. You should be given back a gdb prompt - type "backtrace" at the gdb prompt, and send the output to this bugreport Thanks, -- .''`.Sébastien Villemot : :' :Debian Developer `. `' http://sebastien.villemot.name `- GPG Key: 4096R/381A7594
