--- Comment #2 from ZombineDev <petar.p.kirov at gmail.com> ---
Agreed. From my superficial understanding of dmd's internals, I think the
culprit is around `needsCodegen()`. AFAIR, changes to that code often led to
regressions and undefined symbol references and in the past 3-4 years it was
relatively often tweaked, though I think it was stable / unchanged over the
last year or so.
I don't remember if Walter and Kenji agreed that they have reached the perfect
design, so that no further changes to the general emission strategy were
necessary, but judging from these bug reports, there's still work to be done.
