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.
