This bug most probably caused by bug in gcc's alias analysis, namely http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22591
which is still present in debian's gcc (4.0.1-2) but fixed in current 4.0 branch. There are at least two solutions: either wait for next debian revision of gcc package or recompile mozilla with -fno-strict-aliasing. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
