The bug seems to affect all versions since gcc 3.0 when the option was introduced (including 3.2-branch, 3.3-branch and mainline). The bug seems to be target-dependant, since I cannot reproduce it on mips-sgi-irix6.5. Regards, Volker http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=9088
