Thanks Ondrej.
In the meantime, I've found the problem and am testing a fix. Basically
the function that computes the magic number for a given bit size doesn't
sign-extend it to the full size. In the given example, the signed
divisior +60 for 32-bit produces the multiplicand $88888889. However,
under x86_64, it is not sign-extended to the full 64-bit internal
type... that is, the variable holds $00000000 88888889 instead of
$FFFFFFFF 88888889. This causes a later condition that checks if the
value is less than 0 to malfunction.

Hello it looks like only people with FPC developer status can move
issues to the FPC project. Therefore I forward the request to fpc-devel.
