You are right there because it dies with an arithmetic exception and
not with a Segmentation Fault which leads me to an idea.

The alpha CPU does *not* implement the MIEE standard, thus being fast.
Programmers who expect divisions by zero to return a NaN will be
disappointed. But you can force this behaviour by accepting a
performance penalty with a special compiler flag. I'll try that at
home tonight.

Did you just try the email adress of the original maintainer or did
you any further research ? Maybe some group member of the MIT group
can assist in finding a responsible person ? Maybe the bug submitter
(Mrs. Hoef-Emden) who has some additional knowledge in the area can
help location the author(s) or at least some person remotly involved ?
