Honza/Martin.  Would you mind taking a look at this, or at least provide some
guidance?

A similar ICE to this one starts appearing around rev@159507 for the provided
testcase:

    2010-05-17  Martin Jambor  <mjambor@suse.cz>

        * cgraph.h (cgraph_indirect_call_info): New fields anc_offset,
        otr_token and polymorphic.
        * cgraph.c (cgraph_create_indirect_edge): Inilialize the above fields.
        (cgraph_clone_edge): Copy the above fields.
        * tree.c (get_binfo_at_offset): New function.
        * tree.h (get_binfo_at_offset): Declare.
        * ipa-prop.h (enum jump_func_type): Added known_type jump function
...
...

There is also a set of related patches to ipa*/cgraph* around this time frame
by both of you.

Thanks.
