The same bug does not occur with the latest compiler, but I think that's because an earlier pass of the compiler has optimized the problem away before it trips the bug. Initial investigation suggests this is a problem with reload_combine(). http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8896
