stor-layout: Reject forming arrays with elt sizes not divisible by elt alignment [PR97164]
...
As mentioned in the PR, since 2005 we reject if array elements are smaller
than their alignment (i.e. overaligned elements), because such arrays don't
make much sense, only their first element is guaranteed to be aligned as
user requested, but the next element can't be.
The following testcases show something we've been silent about but is
equally bad, the 2005 case is just the most common special case of that
the array element size is not divisible by the alignment. In those arrays
too only the first element is guaranteed to be properly aligned and the
second one can't be.
This patch rejects those cases too, but keeps the existing wording for the
old common case.
Unfortunately, the patch breaks bootstrap, because libbid uses this mess
(forms arrays with 24 byte long elements with 16 byte element alignment).
I don't really see justification for that, so I've decreased the alignment
to 8 bytes instead.
