Dear Maintainer, I install "julia" (and yes it automatically installs "libopenblas-base" again) and run it. The result is as follow: julia> versioninfo() Julia Version 0.3.2 Platform Info: System: Linux (x86_64-linux-gnu) CPU: Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz WORD_SIZE: 64 BLAS: libopenblas (NO_LAPACKE DYNAMIC_ARCH NO_AFFINITY Sandybridge) LAPACK: libopenblas LIBM: libopenlibm LLVM: libLLVM-3.5
Beside, I have found more information about the crash: -- If I just run "octave", then "inv(a);" will crash. -- If I run "octave -f", then "inv(a);" will NOT crash. -- If I run "octave -f" and then "pkg load ltfat;", then "inv(a);" will crash. The following is the status of some packages: ii libopenblas-base 0.2.12-1 amd64 Optimized BLAS (linear algebra) library based on GotoBLAS2 ii octave-ltfat 2.0.1-1 amd64 Large Time/Frequency Analysis Toolbox ii octave-ltfat-common 2.0.1-1 all Large Time/Frequency Analysis Toolbox (arch-indep files) Would the above information be helpful for debug? Thank you maintainer. ------------------ Original ------------------ From: "Sébastie Villemot"<sebast...@debian.org>; Date: Sat, Sep 5, 2015 05:50 AM To: "Wang S"<wangs...@inhand.com.cn>; "794443"<794...@bugs.debian.org>; Subject: Re: [Pkg-octave-devel] Bug#794443: octave: should not recommendlibopenblas-base Control: reassign -1 libopenblas-base 0.2.12-1 Dear Wang, Le lundi 03 août 2015 à 14:39 +0800, Wang S a écrit : > Octave crashes when inverting matrices sized 10x10 or bigger > if libopenblas-base is installed. > And after I remove libopenblas-base, octave does not crash. Actually the bug that you experience most likely comes from openblas, not from octave. I'm therefore reassigning this bug to the right package. Note that openblas uses different codepaths depending on your CPU, so I need more information to move forward. In order to get more information about your setup, could you please install the "julia" package (it will pull openblas again), run "julia" at the shell prompt, then type "versioninfo()" at the julia prompt. For information, here is the output on my machine: julia> versioninfo() Julia Version 0.3.10 Platform Info: System: Linux (x86_64-linux-gnu) CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz WORD_SIZE: 64 BLAS: libopenblas (NO_LAPACKE DYNAMIC_ARCH NO_AFFINITY Haswell) LAPACK: libopenblas LIBM: libopenlibm LLVM: libLLVM-3.5 Thanks, -- .''`.
