Follow-up Comment #2, bug #37231 (project octave):
(Sorry my memory was a bit hazy)
ARM CPU you wrote? It occurred to me that your problem probably refers to an
issue related to libblas.dll that hasn't popped up for quite a while. See
e.g., bug #35769.
The symptoms are on the one hand unpredictable (i.e., where and when), OTOH
usually lead to a segfault.
In short, you'll have to experiment with the various libblas.dll versions in
your <OCTAVE_INSTALL_DIR>/bin subdir (see below), copying and then renaming
them one by one to libblas.dll until you find one which is stable.
This *is* outlined in the README with the Octave-3.6.2_gcc4.6.2 binary. Did
you care to read that?
I used "demo plotyy" for a fairly reliable crash test; Tatsuro advised
something like (IIRC):
a = randn (30, 100) + randn (30, 100) * i;
b = a * a;
FYI, in my <Octave-3.6.2_gcc4.6.2>/bin subdir I have:
C:\Programs\Octave\Octave3.6.2_gcc4.6.2\bin>dir libblas.dll.*

libblas.dll.ref is the reference BLAS which /should/ work on most, if not all,
architectures - but it is also the slowest.
