I can't reproduce the issue with the attached testcase but the similar looking
ICE in PR51765 can be reproduced with

gcc> make check-g++ RUNTESTFLAGS="--target_board=unix/-flto
dg.exp=cpp0x/variadic-init.C"

Honza, can you have a look?

This seems to be another manifestation of the alias partitioning issues.  I am
testing a fix.

    * lto-cgraph.c (compute_ltrans_boundary): When alias is in the boundary,
    add its target too.
    * lto.c (add_references_to_partition): Add also aliased nodes.
    (add_cgraph_node_to_partition,
    add_varpool_node_to_partition): Work on nodes, not functions/variables;
    when adding alias, add also the aliased object.

    * gcc.dg/lto/pr52634_1.c: New testcase.
    * gcc.dg/lto/pr52634_0.c: New testcase.

Both the testcase and make check works for me now.
