    Not for GCC it isn't. Our standards say that a compiler crash, for any
    input whatsoever, no matter how invalid (even if you feed in line noise),
    is a bug. Other than that we shouldn't make promises, though the old gcc1
    behavior of trying to launch a game of rogue or hack when encountering a
    #pragma was cute.
