--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- I can build the preprocessed source when changing the long long size_t and friend types to 'long'. But then I cannot reproduce the segfault with -std=c++1z -g -O2, it might require MS ABI stuff if it occurs in the dwarf output machinery, I checked on x86_64-linux.
