I don't know why clang complains, it accepts this, which shouldn't be any
different:
char _M_bytes[sizeof(decltype(_M_p))];

It doesn't accept your example for C++98, too. C++11 is fine.
markus@x4 ~ % cat test.ii
union u
{
const char *_M_p;
char _M_bytes[sizeof (_M_p)];
};
markus@x4 ~ % clang++ -std=c++11 -O2 -c test.ii
markus@x4 ~ % clang++ -O2 -c test.ii
test.ii:4:25: error: invalid use of non-static data member '_M_p'
char _M_bytes[sizeof (_M_p)];
^~~~
1 error generated.
markus@x4 ~ %
This looks correct to me.

See § 5.1.1-13 for C++11 and § 5.1-10 for C++98.
The C++98 standard doesn't mention unevaluated operands.

Oh it's only for 98, I see.
Well it's easy to fix with sizeof(const char*) anyway.

There's another instance of the same error later in the file:
