The following causes the linker to complain about missing Foo!string.__xopEquals and .__xtoHash: --- struct Foo(I) { I i; } struct Bar(I) { I i; } static assert(is(Foo!(Bar!string))); --- Workaround is to explicitly instantiate the template: alias Workaround = Foo!(Bar!string);

Happens only for builds without the -debug flag.

In Windows, `-m64` or `-m32 -g` can reproduce same link-failure. https://github.com/D-Programming-Language/dmd/pull/4587
