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include/bug1.h:1:9: warning: #pragma once is obsolete
