[Numpy-discussion] Eigenvalues hangs

Hi all,

Robert Kern suggested to transfer a discussion that originated
on comp.lang.python to this mailing-list.

My problem is that on my platform the numpy 'eigenvalues' method
hangs forever.

Some platform info:
    * numpy 0.9.4 (from the tar.gz)
    * Linux Mandriva (gcc 4.0.1).
    * no optimized BLAS version used.

Greg Landrum pointed out that it may be a gcc 4.0 related problem and
proposed a workaround -- to add the option '-ffloat-store' to CFLAGS.

Could anybody tell me how I should modify the numpy sources to test
this workaround ?

Regards,

SB
