> Oh, you're right. No harm so far since LISP_ALIGNMENT is 8 on current platforms.
For 64bit float, a LISP_ALIGNMENT greater than 8 would imply
a significant amount of waste (same for cons cells on 32bit systems).
So I think it'll stay at 8 for the foreseeable future (which doesn't
mean we can't decide to use large alignment for some other objects, of
course).
