--- Comment #10 from Mikael Pettersson <mikpe at it dot uu.se> 2011-02-05 15:19:22 UTC ---
This was fixed for 4.6 by r159907:

Author: hubicka
Date: Thu May 27 02:07:01 2010
New Revision: 159907

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=159907
Log:
    * cgraphunit.c (verify_cgraph_node): Do checking that DECL match
    edge only when checking is enabled; check using former_clone_of;
    check inline clones too.
    (cgraph_materialize_clone): Record former_clone_of pointer.
    (cgraph_redirect_edge_call_stmt_to_callee): Assert that we are not
    combining redirections; dump args_to_skip bitmap
    (cgraph_materialize_all_clones): Do no redirection here.
    * ipa-inline.c (inline_transform): Do redirection here.
    * cgraph.h (struct cgraph_node): Add former_clone_of filed (enabled
    cheking only).

The patch doesn't apply as-is to 4.5.2 so I haven't checked if it solves the
bug there too.
