Yep, that's what I thought, too.  It must be some configury goof at some place.
The double -> int conversion is just a reduced example.  Basically all the
double fp operations are not working.

If you have some time, it'd be helpful if you could dig a bit deeper.  If not,
I'll have a look myself some time later.  The above is enough of a hint for me,
