So, I seem to have started this discussion off in a bad direction with
my comment about gcc.  I agree that a solution that is guaranteed to
work provided that such a solution exists is preferable to something
that happens to work.  My comment about gcc was mostly curiosity.

Would it be sufficient to have either an implementation of memset or a
function that called memset taking a pointer to volatile data as

The other option seems to be to declare all key material volatile.
That might have negative performance consequences that would be nice
to avoid.
