Update of bug #52473 (project octave):

             Open/Closed:                  Closed => Open                   


Follow-up Comment #5:

I'm seeing this problem now with a build of 4.2.1 (hg id  1327ea4f5a93+;
difference from repo is due to a one line mxe-octave patch for gnulib) using
the latest mxe-octave (hd id cd94e0f04e87+ tip @; difference from repo is just
to set the Octave version number to 4.2.1+).

The crash happens reliably for

[l, u] = lu ([1,2; 3, 4])

I configured mxe-octave with

--with-ccache --enable-octave=stable --enable-binary-packages
--enable-devel-tools --enable-windows-64 --enable-qt5 --disable-system-opengl

I can't blame OpenBLAS here because I also copied librefblas.dll to
libblas.dll and the problem persisted.

I had this problem a few days ago, then did a complete fresh build and install
and the issue disappeared.  But now it's back and I have no idea what is
causing it.
