The problem is quite simple, the POS x87 is using extended double precision
even with us not asking for it.

The only solution would be to spill all intermediaries to stack prior to using
them, which would kill performance big time. The only decent fix is to switch
mono to use SSE for FP, which will be done by the end of this GSoC.
