Bug#995450: buster->bullseye: octave segfaulting during configure (seems unrelated to #992405)

So it seems that your problem is somehow related to multithreading
(with pthread) in openblas.

However I fail to understand the relationship with cdo. Could you
please expand on that?

I happen to have access to a machine with exactly the same CPU (and
Debian Bullseye). I fail to replicate your problem there. I can start
octave with libopenblas0-pthread and there is no segfault.

So there must be another factor at play.

Do you confirm that octave and all its dependencies are pristine Debian
packages from Debian Bullseye? (and not binaries compiled by yourself
or packages obtained from another suite)

Is there something special in /usr/local?

Is the segfault triggered by some computation? In particular, is there
something in your ~/.octaverc, ~/.config/octave/octaverc or
/etc/octaverc?

Is the result different if your run “octave-cli” instead of “octave”
(to disable the GUI)?

Best,
