--- Comment #13 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-01-19 09:34:07 UTC --- Created attachment 26375 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26375 libxul link error log BTW I've first observed this bug while building a PGO-LTO Firefox. The errors of the final libxul link are attached (unrelated warnings have been deleted). As you can see there are ~350 (closely related) errors altogether.
