             Bug #: 52376
           Summary: [4.7 regression] ICE in lto_input_tree_ref, at
                    lto-streamer-in.c:266 while linking LTO-PGO libxul
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: markus@trippelsdorf.de


While linking libxul of a LTO-PGO Firefox build, I get this ICE:
...
In member function ‘HandleComment’:
lto1: internal compiler error: in lto_input_tree_ref, at lto-streamer-in.c:266
Please submit a full bug report,
with preprocessed source if appropriate.

Delta reduction points to a single input object file:

In member function ‘HandleComment’:
lto1: internal compiler error: in lto_input_tree_ref, at lto-streamer-in.c:266
Please submit a full bug report,

The error above only happens with "-fprofile-use" and "-fno-fat-lto-objects".

With "-fprofile-use -flto" I get:
...
/var/tmp/mozilla-central/content/xml/document/src/nsXMLContentSink.cpp: In
member function ‘nsXMLContentSink::HandleComment(unsigned short const*)’:
/var/tmp/mozilla-central/content/xml/document/src/nsXMLContentSink.cpp:1195:54:
internal compiler error: in emit_move_insn, at expr.c:3435

But I don't know how to reduce the testcase further, because it depends 
on nsXMLContentSink.gcda data.

It's part of the "unreduced testcase" tar-ball.
