That's a use case where the dreaded -allinst was added for: seperate compilation with different version, debug or unittest settings. In that case the template emission optimization fails to work because it assumes that the template is already emitted.

It's a bit strange that the optimization does not also avoid generating any code for the unittests, though.

confirmed that adding -allinst works (both with dmd and ldc), but indeed, this
should be fixed.

question: what are downsides of -allinst?

downsides are slower compilation and bloated object files. Should not make a difference in the size of the executable.
