Yes,
------------------
struct Class1 {
int member_;
};
int &f(Class1 *a) { return a->member_; }
------------------
also generates the warning.
This is a bug, right? I'm basing this issue on
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#Common-Function-Attributes
saying "Note that a function that has pointer arguments and examines the data
pointed to must not be declared const if the pointed-to data might change
between successive invocations of the function."
