Isn't this a Windows problem rather than a Lua problem? The problem
being that various libraries secretly like to change the Floating Point
Control register and don't always change it back. You know the kind of
thing, you call a DirectX function which calls some dodgy "high
performance" graphics driver and now all of your NaNs are signalling
and the floating point exceptions are of the non-useful kind. Or your
rounding mode has changed.
