Since a few weeks, running the test suite after installation on Windows (10)
Octave crashes consistently on lu.cc-tst. I've managed to capture a screenshot
just before Octave disappears from the screen, see attachment.
After moving lu.cc-tst out of the way Octave crashes on qr.cc-tst. With that
test Octave crashes too fast to get a screenshot.
I didn't investigate further which other tests might make Octave crash as
well.

The PC's I tried on have Intel Core i5 (10 yrs old), AMD Ryzen 7 and (virtual)
Xeon CPUs, so I guess hardware isn't the problem.
Qt version seems irrelevant as this started before the switch to Qt6 in
mxe-octave.
I tried with OpenBlas and reference Blas, no difference either.
So it looks like some other math library (than blas) might be the culprit.

I crossbuilt Octave-9.0.0 with fortran 64bit indexing incl all of mxe-octave
anew.

The last months I have only occasionally made crossbuilds so I have no exact
idea when it started. Crossbuilds from before the summer run fine.

Do we have dev Octave nightly builds that I can try?
