------- Comment #25 from tromey at gcc dot gnu dot org 2006-12-29 07:58 -------
FWIW I've been looking at this area for PR 29966.
I don't see how overflow checking could be added to
_cpp_lex_direct. However I did end up adding an
assertion to _cpp_lex_token, to try to expose a hidden
assumption:
if (pfile->cur_token < pfile->cur_run->base
|| pfile->cur_token >= pfile->cur_run->limit)
abort ();
I also looked at the other assignments to cur_token
and (aside from the one fixed in my forthcoming patch)
they all look ok.
So, I think this PR can be closed.
Please reopen if you think I've done this in error.
