System: NetBSD NetBSD-4-0.Rodents.Montreal.QC.CA 4.0 NetBSD 4.0 (GENERIC) #0: 
Sun Dec 16 00:20:10 PST 2007 
Architecture: i386
Machine: i386
        When run on a suitable input file, the compiler crashes:

        cc: Internal error: Illegal instruction (program cc1)
        Please submit a full bug report.
        See <URL:> for instructions.

        Reading /usr/src/gnu/dist/gcc4/gcc/doc/bugreport.texi leads me
        to think the FSF considers this a bug, so they presumably want
        to hear about it.
        (echo int i =; dd if=/dev/zero bs=1048576 count=10 | tr \\0 \() > z.c
        cc -c z.c
        None.  This is a contrived case, of course.  The gcc shipped
        with 4.0 uses a recursive-descent parser, whicih this is
        designed to run out of stack.  Nor is the crash unexpected
        given the input, or, really, even harmful (thus
        non-tricial/low) - but bugreport.texi indicates the FSF
        considers it a bug anyway.
