--- Comment #17 from Nicholas Krause <xerofoify at gmail dot com> ---
Sorry about that. I've managed to track it down to a problem with a alias issue 
And from reading the code in the original cvs commit. I'm not able to read it
currently but the original function mentioned seems to now be
cgraph_edge::verify_corresponds_to_fndecl. I've tried to access the original
commit but it complains about permissions. Maybe I'm wrong but this seems very
odd to me:
node = node->ultimate_alias_target ();

is basically referring to itself meaning:
if (callee->former_clone_of != node->decl
      && (node != node->ultimate_alias_target ())
      && !clone_of_p (node, callee))

the && (node != node->ultimate_alias_target ()) is basically referring to
itself when comparing yet its already being defined equal to the return value
of ultimate_alias_target meaning its always true. Not sure if this fixes this
bug or something else. Thoughts?
