  * Fix coredumping bug on ppc: Ubuntu bugzilla:
     http://bugzilla.ubuntu.com/show_bug.cgi?id=13771
    This is the same issue as
     http://bugs.ghostscript.com/show_bug.cgi?id=687643
     http://bugs.ghostscript.com/show_bug.cgi?id=687730
    discussed in
     http://ghostscript.com/pipermail/gs-code-review/2004-September/004649.html
    and probably the same as Debian bug #324796 and perhaps others in
    Debian's gs-esp.

    This bug is due to gs's incorrect assumption that (where ref is an
    important struct inside gs) sizeof(ref) % alignof(jmp_buf) == 0.  This
    is not true on ppc and apparently not necessarily on Itanium either.

    The `fix' I have applied is to wrap setjmp/longjmp up in macros which
    arrange for jmp_buf to have alignment 1, as sketched out in the URLs
    above.  A previous attempt to fix it by padding ref out to the
    alignment of jmp_buf failed and I don't know why; but I suspect other
    unjustified assumptions in gs.

    GhostScript's algorithms ought to be repaired not to assume
    falsehoods.
