------- Comment #14 from armin76 at gentoo dot org  2010-04-29 19:36 -------
I tried to bisect it, however there is an issue:

gcc failed to build since
http://repo.or.cz/w/official-gcc.git/commit/598767c938d0d001bbbe41e0a189104bb53e3580

Gives this error:

Please submit a full bug report,

See <http://gcc.gnu.org/bugs.html> for instructions.
make[3]: *** [lambda-code.o] Error 1

That error was fixed with
http://repo.or.cz/w/official-gcc.git/commit/9dbb96fec5e08762f97dda771522283f1fe9710f

However we now got that error of what this bug is about.
