See http://gcc.gnu.org/ml/gcc-patches/2013-04/msg00003.html.  Either the
backport of 56077 should be reverted or, if the ICE is coming from a different
place, Maxim's patch is applied instead.

Sure, then I'll revert the patch after testing -- Richi, are you fine with
that?

backporting r190733 fixes the issue too, testsuite still running

Please revert for 4.7.3 and re-apply for 4.7.3 with the additional backport.

I guess you mean revert for 4.7.3 and re-apply for 4.7.4 with the additional
backport ;)
