           Summary: [4.8 Regression] ICE : in
                    cgraph_mark_address_taken_node, at cgraph.c:1409
    Classification: Unclassified

The following ICE happens during the last stage of a lto/pgo build of Firefox:

 internal compiler error: in cgraph_mark_address_taken_node, at cgraph.c:1409

I've managed to reduce the testcase from ~3000 input files to 34,
but unfortunately not further.
