I think it does do different code ... when it stores an int into a
void* .... I don't think it will convert it to long first ... it
shouldn't acuse arithmetic traps ... and probably not even unaligned
accesses ... but it's just a guess .... I don't think gcc thinks of
void* as a data storage so it will just write to it's location ...
(but it's completely just a gues and I'm probably wrong) ... so then
casting to long should solve it then ...

I can't produce them ... I run linux/alpha 2.1.85 ...
