--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The problem is that cpp_peek_token, if it returns CPP_EOF, is fatal in the
preprocessing:
do
{
peektok = _cpp_lex_token (pfile);
if (peektok->type == CPP_EOF)
return peektok;
}
while (index--);
but the macro_to_expand stuff (for which cpp_peek_token has been written, BTW)
really assumes that it can non-destructively peek tokens when needed.
