Oh yeah, in memory profiling grades we allocate an extra word before the
object for the allocation id, so the start of the object would not be 64
bit aligned. We would need to allocate an extra two words, or find
The old (now useless?) term size profiling stuff used the same trick.
In handle_options.m we disable double-word fields in term size profiling
grades, but curiously not in memory profiling grades. I'll check it when
I get a chance.
