Has anyone seen mainline Fortran regression with SPEC CPU 2000/2006?

[H. J. Lu]

Gcc 4.3 revision 118764 failed galgel in SPEC CPU 2000 with
-O2 -ffast-math on Linux/x86-64. I got

galgel_base.o2[30363]: segfault at 000000000000000b rip 000000000000000b rsp 0000007fbffff008 error 14

Gcc 4.3 revision 118723 passes SPEC CPU 2006 with -O2 -ffast-math on
Linux/x86-64. But it fails wrf in SPEC CPU 2006 with -O2 on Linux/x86.
The odd thing is the test input works fine and the ref input causes
segfaults at the very end of the several hour run.

Has anyone else seen it?
