I think the pointer would become invalid after the next sequence point,
but I am not sure.

The standard itself is pay-for-play, but committee draft WG14/N1124
is free, and I believe that it has the same section numbering and
substantially the same wording. A web search should find it. (I don't
have the standard itself, so when I quote section numbers, I am actually
quoting from the N1124 draft.)
