command used:

./configure -j4 --build-cross-tools-gcc4 x86 ../buildtools/

[kallisti5]

verified same issue with:

./configure --build-cross-tools-gcc4 x86 ../buildtools/

[kallisti5]

aah.

We were discussing this in irc and decided it may be due to my bleeding edge ArchLinux desktop.

kallisti5@eris buildtools :) $ gcc -v

gcc version 4.7.0 20120324 (GCC) 

Bumping priority down because it seems more likely an issue with new GCC versions vs due to a recent commit.

[korli]

Workaround: install an older GCC release until that's fixed GCC side.

[kallisti5]

​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52986 was opened with gcc to note this issue.

[korli]

The solved state of this issue would mean we need to update to 4.6.3.

[kallisti5]

Since the fix was so simple, I cherry-picked it in btrev43031.

Resolved. Next gcc version we update to should already include it.
