--- Comment #13 from Martin Jambor <jamborm at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #11) > Looks like a GC issue as I was reducing the code but removing the comments > and empty lines caused the testcase to no longer crash. Adding --param > ggc-min-expand=1 --param ggc-min-heapsize=1 allowed it to ICE now. Oops, I forgot that struct ipa_node_params is not a GTYed structure. Will do that first thing tomorrow.
