[Pkg-octave-devel] Bug#794443: Bug#794443: octave: should not recommendlibopenblas-base

[Wang S]

Thank you.

In fact, the crash does not always happen when matrix size >= 10x10.

Exactly, in my situation, for the 82x82 matrix "a" in the attach file "a.txt", it will crash.
And I also have tried "for n=1:82 inv(a(1:n,1:n)); end", it will crash when n = 43.

So, would you please have a try of the attach data file "a.txt" with the following script?
> load a.txt
> inv(a)

I cannot reproduce this bug in Octave 4.0:

     $ dpkg -l libopenblas-base | grep ^ii
     ii   libopenblas-base 0.2.14-1     i386         Optimized BLAS (linear algebra) library (shared library)
     $ octave-cli --version | grep version
     GNU Octave, version 4.0.0
     $ echo 'inv(randn(12)); printf("Got here\n")' | octave-cli -q
     Got here

I am hereby marking this bug as fixed in version 4.0.0-3. Should we 
actually close it?
