Comment 1 Andrew Pinski 2007-12-29 19:32:39 UTC

What happens if you add -ffloat-store ?

Comment 2 kargls 2007-12-29 19:44:29 UTC

How is this a Fortran issue?  CBLAS uses C.
What options did you use to build CBLAS?
Is the backing BLAS also built from netlib sources
and with what options was is it?

Comment 3 Andrew Pinski 2007-12-29 19:46:50 UTC

Anyways -ffloat-store fixes the issue so a dup of bug 323.

*** This bug has been marked as a duplicate of 323 ***

Comment 4 Jerry DeLisle 2007-12-29 20:09:34 UTC

CBLAS actually has a few Fortran programs in it.  The default build uses g77 on Linux.  Regardless, I was able to build -m64 and -m32 without any failures using gfortran.
