[Bug c/14205] New: ICE with -M and -include

[1319 at bot dot ru]

When gcc invoked with -M and -include it segfaults on any input files. This
problem happens with c++ also. Easiest way to turn this bug on is:

$ touch file.c file.h
$ gcc -M -include file.h file.c
file.c:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
$

or, easier to debug:

$ cc1 -E -M -include file.h file.c

with same result.
It is at line 70 in c-ppoutput.c: (gcc 3.4.0 20040218)

61:/* Preprocess and output.  */
62:void
63:preprocess_file (cpp_reader *pfile)
64:{
65:  /* A successful cpp_read_main_file guarantees that we can call
66:     cpp_scan_nooutput or cpp_get_token next.  */
67:  if (flag_no_output)
68:    {
69:      /* Scan -included buffers, then the main file.  */
70:      while (pfile->buffer->prev)
80:	cpp_scan_nooutput (pfile);
90:      cpp_scan_nooutput (pfile);
91:    }

here pfile->buffer == 0.

Confirmed but I think this is a dup of bug 14103, can you try again?
