Hmm, wait, I think these are two different issues :)

I managed to successfully use OSSubprocess in 64bits with some tweaks. The problem is that OSSubprocess does some manual type coertions like assumming 32 bits:

collectArgumentPointersInto: aPointer

�� �� [...]

�� �� aPointer nbUInt32AtOffset: (self argVArguments size - 1) * self systemAccessor sizeOfPointer put: 0

That should probably be replaced by:

�� �� aPointer platformUnsignedLongAt: (self argVArguments size - 1) * self systemAccessor sizeOfPointer put: 0.

Now, those methods depend on UFFI, having UFFI is a must for OSSubprocess.

Good point.�� I'm embarrassed to say I didn't look at the code, just
the comments.

Yep - although this could use <inline: #always>.

I've sent Mariano a message asking him to clarify what he needs from
this PR.�� I'll follow up again after he replies (I'm keen to see
OSSubprocess on the 64 bit VM).

Thanks!
