Description Forgotten User 55iwwMllzz 2006-02-01 23:32:48 UTC 
Trying to execute functions like:
   octave:1> givens (1, 1)
or
   octave:1> eig(rand(10))

makes Octave hang while using more than 90% CPU.

This bug also affects the Octave package from SuSE 10.0. But it does NOT happen with the SuSE 9.3 package.

This thread:
    http://thread.gmane.org/gmane.comp.gnu.octave.bugs/2479
refers this bug, although the given suggestion that it might be a LAPACK bug does not seem correct since the lapack RPM does not even need to be installed for Octave to run.

I don't think this has anything to do with gcc packages.
Is it possible for you to reate some kind of backtrace here (with gdb or even ltrace)? Maby it runs into an endless cycle. Add any output if there is one.

Please reopen this bug in the case the information asked for can be provided.

Closing old LATER+REMIND bugs as WONTFIX - if you still plan to work on it, feel free to reopen and set to ASSIGNED.

In case the report saw repeated reopen comments, it's due to bugzilla timing out on the huge request ;(
