Follow-up Comment #10:

I backported the patch to exit with info=-2 when a singularity is reached
(http://hg.savannah.gnu.org/hgweb/octave/rev/68e2daa29222).

I added a BIST test on stable to verify that the patch above works correctly
(http://hg.savannah.gnu.org/hgweb/octave/rev/c29a2107c559).

Finally, I checked in a third patch to return a success code (info=1) if the
initial guess for the solution is already accurate enough
(http://hg.savannah.gnu.org/hgweb/octave/rev/b3c35a130f94).  I added a BIST
test for that too.

Marking bug as fixed and closing report.
