--- Comment #2 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- that's a known (to me) problem; it's mentioned in the gOlogy report, and IIRC I even highlighted it in the slides about it I spent some time looking for a low-hanging fix a while ago, but came out empty-handed a fix will likely take involvement by someone a lot more familiar with ivopts than I am (or putting in the time required to become one ;-)
