--- Comment #24 from Iain Sandoe <iains at gcc dot gnu.org> --- Created attachment 46743 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46743&action=edit Make sure we process the PRAGMA_GCC_PCH_PREPROCESS first We need to make sure that we've acted on the PRAGMA_GCC_PCH_PREPROCESS before calling c_common_no_more_pch (), since that's allowed to deallocate resources that are set aside for PCH.
