[Bug preprocessor/17944] [3.4/4.0 regression] ICE with pragma once

Here's a reduced testcase which consists of three files:

PR17944.c:
  #include "include/bug1.h"
  #include "include/bug2.h"

include/bug1.h:
  #pragma once
  #include "bug1.h"

include/bug2.h:
  #include "bug1.h"

Compiling this with "gcc -c PR17944.c" I get a segfault since gcc 3.4.0.
With gcc 2.95.3 - 3.3.5 I just get a warning:
  In file included from PR17944.c:1:
  include/bug1.h:1:9: warning: #pragma once is obsolete
