4.7.3 is fine. 4.8 and 4.9 segfault.

True, although it has been broken (though didn't crash) already around in
r110000:
MALLOC_PERTURB_=225 /usr/src/gcc-test/obj/gcc/cc1plus.110000 -include
./pr58893.h -include xxx.h pr58893.c  -quiet -o /tmp/pr58893.s
<command line>:3947580:58: error: xxx.h: No such file or directory

(note the completely bogus line and column info).

Perhaps open_file_failed should use cpp_error_with_line instead of cpp_errno,
at least when invoked from within _cpp_find_file/_cpp_stack_include with type
== IT_CMDLINE (or IT_DEFAULT?), because pfile->cur_token[0] as well as
pfile->cur_token[-1] points to uninitialized memory at that point.

Tom/Dodji, any thoughts on this?

possible fix

Hi,

I have looked at this issue, and think this is the right fix.

Regarding the hunk in cpp_diagnostic, which is not directly involved
in this bug, but still obviously wrong:

The line "src_loc = pfile->cur_run->prev->limit->src_loc"
is probably unreachable, but will crash it is ever executed.

see:

_cpp_init_tokenrun (tokenrun *run, unsigned int count)
{
  run->base = XNEWVEC (cpp_token, count);
  run->limit = run->base + count;
  run->next = NULL;
}

limit points at the end of the run, prev is uninitialized.

Comments?
