error[E0277]: can't compare `T` with `_` in const contexts
  --> $DIR/call-generic-method-fail.rs:4:8

LL |     *t == *t
   |        ^^ no implementation for `T == _`

note: the trait `PartialEq<_>` is implemented for `T`, but that implementation is not `const`

   = help: the following other types implement trait `PartialEq<Rhs>`:
             <&A as PartialEq<&B>>
             <&A as PartialEq<&mut B>>
             <&mut A as PartialEq<&B>>
             <&mut A as PartialEq<&mut B>>
             <*const T as PartialEq>
             <*mut T as PartialEq>
