Package: libopenblas-base
Version: 0.2.12-1
Severity: important
Dear Maintainer,
* What led up to the situation?
I call the expm() function provided by Octave on a system on which
libopenblas-base is installed.
* What exactly did you do (or not do) that was effective (or
ineffective)?
* What was the outcome of this action?
The program segfaults.
* What outcome did you expect instead?
I expect it to return the correct answer. Removing libopenblas-base (and
therefore using libblas3 instead) solves the problem.
