--- Comment #2 from Markus Trippelsdorf trippels at gcc dot gnu.org ---
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.

This looks correct to me.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64367 --- Comment #3 from Markus Trippelsdorf trippels at gcc dot gnu.org --- See § 5.1.1-13 for C++11 and § 5.1-10 for C++98. The C++98 standard doesn't mention unevaluated operands.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64367 --- Comment #4 from Jonathan Wakely redi at gcc dot gnu.org --- Oh it's only for 98, I see. Well it's easy to fix with sizeof(const char*) anyway.
