I was running the LAPACK with -O3
with 20041212 (snapshot) with Steve Kargl's I/O patch
from http://gcc.gnu.org/ml/gcc-patches/2004-12/msg00844.html
applied.   The test ran OK until xeigtsts segfaulted:

Reverting Steve's patch, bubblestrapping and rerunning it made
no difference.

This is a regression from about a month ago, and possibly a target
problem.
