--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
For the ICE in this bug it might be enough to, in cgraph_node::release_body,
walk callees and zap ->call_stmt on the cgraph edges.  But the more general
issue remains - GC will still try to collect the now unreferenced stmts and
follow the link to the ggc_free()ed basic-block.
