Ah, sorry, that was for #39834 - wrong issue! Disregard.

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.
