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). Stefan
