Agreed, and I'll even grant your point that if it is an HPUX-specific
or IA64-specific bug, it is not worth spending huge amounts of time
to isolate.  The problem is that we don't know that.  What we do know
so far is that if it can occur elsewhere, it's rare --- so we'd better
be prepared to glean as much info as possible if we do get such a
failure.  Hence my thought of s/ERROR/PANIC/.  And I'd be in favor of
any other low-effort change we can make to instrument the case better.
