[Octave-bug-tracker] [bug #63384] [MXE Octave] Error for "inv" with default branch

[Dmitri A. Sergatskov]

Follow-up Comment #15, bug #63384 (project octave):

FYI --
There are two tests failing with lapack-3.11 (inv and xinv):


processing /home/dima/src/octave/clang_opt/libinterp/corefcn/inv.cc-tst
***** warning <rcond = > assert (inv (NaN (2,2)), NaN (2,2))
!!!!! warning failed.
Expected warning <rcond = >, but got error <ASSERT errors for:  assert (inv
(NaN (2, 2)),NaN (2, 2))

  Location  |  Observed  |  Expected  |  Reason
   (1,1)         Inf          NaN        'NaN' mismatch
   (2,1)         Inf          NaN        'NaN' mismatch
   (1,2)         Inf          NaN        'NaN' mismatch
   (2,2)         Inf          NaN        'NaN' mismatch>

***** test
 [xinv, rcond] = inv (NaN (2,2));
 assert (xinv, NaN (2,2));
 assert (rcond, NaN);
!!!!! test failed
ASSERT errors for:  assert (xinv,NaN (2, 2))

  Location  |  Observed  |  Expected  |  Reason
   (1,1)         Inf          NaN        'NaN' mismatch
   (2,1)         Inf          NaN        'NaN' mismatch
   (1,2)         Inf          NaN        'NaN' mismatch
   (2,2)         Inf          NaN        'NaN' mismatch



If somebody can write a fortran code that reproduces this test, it would help
to push it upstream.

Dmitri.
