Comment by andreas.raab:

3.9 has a different manifest bit pattern for NaN than Pharo. Try this:

Float nan hex "<print it>"

3.9: '7FF8000000000000'
Pharo: 'FFF8000000000000'

It looks like 3.9 was initialized on PPC, Pharo on Intel. Since there is an infinite number of NaN bit patterns the real solution is to use a manifest binary constant in Float initialization, i.e,

Float class>>initialize
"..."
NaN := Float with: 16rFFF80000 with: 0.

instead of the computation that is in there today.
