I am porting the test for lib.string.access methods (operator[] and at)
and found one issue.

The code=20

#include <string>

int main (void)
{
    std::string s ("a", 1);
    const char& c =3D s[1];

    return 0;
}

results in assertion and fails. But the standard says for=20
const_reference operator[] (size_type pos) const:

"If pos < size() returns data()[pos]. Otherwise, if pos =3D=3D size(), =
the
const version returns charT(). Otherwise, the behavior is undefined."

So I expect charT() without any asserts.

What do you think about this?


Thanks,
Anton Pevtsov.
