Follow-up Comment #1:

Thank you for your bug report and for trying to provide as many details as you
can. If both issues hang in the same way, then I would say it's possible that
it's the same underlying issue. The plot routines are probably also performing
matrix operations, so possibly also hanging on a BLAS or LAPACK routine. Can
you confirm with gdb or possibly ltrace that the hang is in one of the
numerical libraries in both cases?

If this system is an apt-based distribution, it's possible that you are
linking against OpenBLAS even when you think you are linking against the
reference BLAS library due to the alternatives system
<https://wiki.debian.org/DebianAlternatives>. You can try running "version
-blas" in Octave to see what it detects. You can also try completely removing
all traces of OpenBLAS libraries using apt or dnf or whatever your package
manager is. I think your intuition different BLAS and LAPACK is a good start,
but it's not clear that you aren't building with OpenBLAS every time.
