It passes with 2.95, though. Since this seems like a regression to me, I raise the priority. Note that no optimization flags are necessary to trigger this behavior. The same happens with the C++ front end, by the way. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8639
