[Octave-bug-tracker] [bug #61246] matrix inversions give wrong results (inv, lu, mldivide)

[Markus Mützel]

Follow-up Comment #15, bug #61246 (project octave):

I was thinking that we updated OpenBLAS in MXE Octave since the release of
Octave 6.3.0. But looking back on the repository log, that update happened
*before* the release of Octave 6.3.0.

If the error occurs with the "official" installer built by jwe on his systems,
but it works correctly with the installers built on octave.space, it might be
that this is again a case where the issue depends on the  processor on the
build system vs. host system.

IIUC, jwe upgraded to newer systems. Maybe that issue won't occur with the
newer build systems. But as long as we don't understand the actual cause, it's
hard to predict.

Ideally, we would get our build rules for OpenBLAS correct such that the
resulting binaries don't depend on the processor used by the build system.
