From: "goeland86 at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/52811] New: -O3 flag makes xorg-server-1.11.4 compile fail on amd64 Date: Sat, 31 Mar 2012 20:50:00 -0000 [thread overview] Message-ID: <bug-52811-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52811 Bug #: 52811 Summary: -O3 flag makes xorg-server-1.11.4 compile fail on amd64 Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned@gcc.gnu.org ReportedBy: goeland86@gmail.com When compiling xorg-server-1.11.4 with the -O3 optimization flag enabled, the compilation of xorg-server fails in xf86EdidModes.c at line 747, about an array subscript being above array bounds. Recompiling with the -O2 flag the error disappears without any other changes to the configuration. I ran into the problem with gcc-4.5.3 today, but I ran into it several months back, possibly with 4.5.2 (I'm not quite sure, and didn't think it was gcc related at the time.) This happened on Gentoo reportedly to others besides myself, according to echoes in #gentoo on irc.freenode.net.
