Microsoft always has a problem with a long jump to a far pointer
I have seen them screw that up every time
Do you have valid examples of those problems going back to when Windows was written in C? It seems that Safari, an apple entity, has the problem here. Far pointers were common in Windows 3.1 and 16-bit windows in order to adequately access and utilize memory. With the advent of 32-bit systems and flat memory models the need for far pointers disappeared and specifying a pointer as far in 32 bit systems should generate an error. I believe that Win64 systems no longer support a Win16 sub-system so you should not be able to run Win16 apps on a 64-bit system.
