True.  There's something strange going on: SYMENT's alignment is 1
(it's just a collection of char[]), so one of the two pointers passed
to memcpy doesn't have any alignment requirements, and memcpy() must
not copy word-by-word, even if the other pointer has strict enough
alignment requirements.  When I wrote the bug report, I looked at the
assembly code and it used ldr/str (not ldrb/strb) instructions, so the
problem did exist.  Anyway, I cannot recreate the problem.  For now,
just consider the problem to not exist, I'll let you know when it
reappers.
