I wasn't aware of the other segfaults, I'd like to get them all fixed...
The list was meant to elicit additions.

I don't know where the missed floating point errors come from, but they are
somewhat dependent on the compiler doing the right thing and hardware
support. I'd welcome any insight into why we get them on SPARC (underflow)
and Windows (overflow). The windows buildbot doesn't seem to be updating
correctly since it is still missing the combinations method that is now
part of the test module.
