 Interestingly, this bug is very similar to one that I reported a long
 time ago (PR 228) and that was also fixed a long time ago:
 
 http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view&pr=228&database=gcc
 
 This old bug is still fixed with gcc-3.0 - so maybe the fix of the old
 bug introduced the new one?
