--- Comment #3 from Matthias Klose <doko at gcc dot gnu.org> 2012-11-21 04:07:53 UTC --- this seems to be a configuration issue. the plain cvs build does succeed, however if you turn on -fstack-protector by default, the build fails. this is the patch I'm using to turn on -fstack-protector by default: http://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-4.7/debian/patches/gcc-default-ssp.diff?view=markup
