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.

Please don't expect people to download a whole package, you have the files
already so you can provide the preprocessed source for the file that fails to
compile.
See http://gcc.gnu.org/bugs/

Apologies. I will upload the proper files as soon as possible - at the moment I
have gentoo installing the whole system having fixed the bug. I will re-create
the conditions tomorrow and upload the required data then. I was told to report
this bug to gcc, and have been a bit hasty.
