--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- I wonder if somebody can provide a tarball of sources to generated the PCH (maybe a tarball of preprocessed sources?) and preprocessed source up to the PCH? Otherwise can you add -fdump-rtl-expand-details and attach the dump produced from the crash?
