Doh, thanks. Turned out to still miss a few cases where it wasn't
checking for memoryless nodes (Andi explains why I didn't see it
with x86-64: because it handles the case differently and assigns
the default node to the nearest one with memory. I think).

Working on a new version, so I've definitely got your bug covered
now :)
