    Bug 699668: handle stack overflow during error handling
    
    When handling a Postscript error, we push the object throwing the error onto
    the operand stack for the error handling procedure to access - we were not
    checking the available stack before doing so, thus causing a crash.
    
    Basically, if we get a stack overflow when already handling an error, we're out
    of options, return to the caller with a fatal error.
