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  <mjam...@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.
