<div>
<pre>template <typename T> int f(T *) { return 0; }
struct Foo {
union {
int n = f(this);
};
} g;
Clang considers the union here to be a distinct record, and produces the
following template instantiation:
??$f@T<unnamed-tag>@Foo@@@@YAHPAT<unnamed-tag>@Foo@@@Z
MSVC considers 'this' to be of type Foo*, and gives this instantiation
mangling:
??$f@UFoo@@@@YAHPAUFoo@@@Z</pre>
