------- Comment #3 from uros at kss-loka dot si  2005-10-14 12:55 -------
The testcase could be furhter reduced into perhaps the smallest testcase that
ICEs, ever (name this file for example ttt.i):

--cut here--
#
--cut here--

gcc ttt.i
ttt.i:1: internal compiler error: Segmentation fault

Leaving as P2.  This really should be fixed.

------- Comment #5 from bothner at gcc dot gnu dot org  2005-10-31 16:58 -------
The two test cases appear to be unrelated problems.

The inital report is because an invalid line marker is seen before debug_hooks
is set in process_options.  fe_enter doesn't normally see an LC_ENTER during
read_original_filename.
One possible fix to to initialize debug_hooks statically in toplev.c:
const struct gcc_debug_hooks *debug_hooks = &do_nothing_debug_hooks;

The other testcase is because _cpp_pop_buffer is called prematurely, because
the code doesn't know we're in a directive.
A possible fix for that is to set/clear pfile->state.in_directive areound the
second _cpp_lex_direct in read_original_filename:
  if (token->type == CPP_HASH)
    {
      pfile->state.in_directive = 1;
      token1 = _cpp_lex_direct (pfile);
      _cpp_backup_tokens (pfile, 1);
      pfile->state.in_directive = 0;

I haven't updated my cvs archive yet, but if someone coudl volunteer to test
these fixes that woudl be appreciated.

I can test the first one since it is an easy one to test.
