--- Comment #4 from Mick P. <mick.pearson at wildblue dot net> ---
Sorry, here is an example diagnostic. The reason I couldn't follow it yesterday
is "make -j4" was causing the output to be scrambled.

I just meant to explain the underlying problem, since it's a different problem.
I can't get code highlighting to work with ``` or {{{. T would be something
like the following:
template<class A, int A::*> struct T{};
Maybe this link works? https://godbolt.org/z/fYEYGP
Output is similar:
template<class A, int A::*> struct T{};
struct A{};
struct B:A{ int x; };
struct C:A{ T<A,(char A::*)&B::x> y; };
I don't know, for casting purposes this seems logical, like something should
work, and had worked before.
