Re: [Gc] Alignment/padding of small objects on 64-bit platform (x86-64)

That is okay with me... At the moment the GC allocates memory in chunks of
16 bytes, so I lose 8 bytes everytime I allocate a 24 byte block.

Would lowering the granule size to 8 bytes likely cause any problems? (If
most of my allocations are small...)

Regards, Stefan.
