--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The #c3 testcase works now, so if you have something different you can
reproduce it on, please attach preprocessed source for the PCH header and
preprocessed source of the c/c++ source with the PCH header unincluded plus
command lines.
