So far I have no clue whatsoever how IPA-SRA comes into this (but it is true that switching it off makes the ICE go away) or how the MEM_REF patch makes anything any different (the IPA-SRA modification that seems to trigger this only removes a parameter, it does not build any memory references). Nevertheless, by adding verify_cgraph() calls all over the place, I figured out that the verification becomes unhappy after the following call in expand_call_inline. fn = cgraph_node (fn)->decl; cgraph_node creates a cgraph node if it does not find one so I guess that is a part of the problem.
