Note: this is very old, I barely remember it.

No, I think I am saying: hello, this is the left hand side of a ->* operator,
and you are feeding me a pointer to member, which obviously should be on the
right hand side.

The testcase in the patch has p ->* p, and clang says:
test.cc:2:11: error: left hand operand to ->* must be a pointer to class
compatible with the right hand operand, but is 'struct A::*'
int i = p ->* p ; // { dg-error "" }
^~~
.*
(not sure what that .* is doing there)

IIRC (and I could be wrong), this test is really about the lhs. Which doesn't
mean that the error message is good...
