I wonder why glibc silently overaligns aligned_alloc() without reporting
an error for an alignment of 2, while it reports an error for an

Why doesn't it make sense?
If the underlying memory management system supports only some
power-of-two alignments including one alignment greater than 2, it is
easy to support alignment of 2 by overaligning, but it is not possible
to support an alignment of 3.
