I believe this patch will fix optimization/6703:
http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=6703
It also fixes a miscompilation of mozilla bug #145267:
http://bugzilla.mozilla.org/show_bug.cgi?id=145267
BTW, I had a few more testsuite failures when I added this patch.
I'm not sure if it's related though... anyone else get these errors?
