FWIW, `volatile' might not necessarily give us the behavior we
want/need.  IOW if the warning is legit, we should investigate and
decide exactly how to fix the problem (which might involve using
`volatile' or it might on the contrary involve making a copy of the
current value).

If the warning is not legit, then it's a problem in GCC and we shouldn't
do anything on our side other than report a bug.
