[Octave-bug-tracker] [bug #35021] Floating point exception on matrix multiplication

[Melvin Robinson]

Follow-up Comment #8, bug #35021 (project octave):

What is UB?  Do I really want to know? :)

No, the problems seem to have gone away when rebuilding with the serial
library.  I opened a ticket with them and hope to help troubleshoot this issue
some more.  

The configure options that I used for Octave are:
--with-lapack=-lptlapack --with-blas=-ltatlas

which are the parallel versions created with the ATLAS build.

So, Octave would receive these fp exceptions from the ATLAS routines.  Is
there a way to find out more information?
