It should be noted that if the "function calls abort ()" message is
unpalatable for some reason (e.g, lack of specificity), these can be
replaced with something more suitable over time.  In each case, the
choice of a more suitable message will likely depend upon the context,
so I think that Andrew's suggestion is a reasonable first step.  It is
certainly better than what we have now...
