Test case:

void foo(int)
{
    static struct S {}
    pragma(msg, " ", S.mangleof);

    void bar() {}
    pragma(msg, bar.mangleof);

    int var;
    pragma(msg, var.mangleof);

    template X(T) {}
    pragma(msg, "  ", X!int.mangleof);  // !
}
version(bug) void foo() {}

Without "-version=bug"

_D4test3fooFiZv3vari
  4test3fooFiZv8__T1XTiZ  <----

With "-version=bug"
