Sam James <sjames at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |GC --- Comment #14 from Sam James <sjames at gcc dot gnu.org> --- OK, I think it might be a GC issue. It's very sensitive to small changes (clang-format, for example, makes it work). The preprocessed version also works. But note that it has a bunch of __FILE__ and __LINE__. I've rigged it up to use gimple-match-6.cc so right now, it still needs gimple-match-auto.h.
