Right.  While I'm not extremely knowledgeable about the process, since
that string is associated with Qarith_error (in data.c), I assumed it
was probably some code deeper down raising the exception (from either
data.c or floatfns.c).  Given the fact that it only happens on i386, I
also wondered if x87 issues might be involved -- but the fact that it
only happens on *this* i386 machine (and a couple of others) suggests
the software versions matter.

In any case, if we can come up with some suitable diagnostic process, I
can ask the buildd maintainers to attempt it, but since I'm sure there
time is a limited resource, I wanted to consult all of you in an attempt
to test more efficiently.

Thanks
