--- Comment #8 from kinke <kinke at gmx.net> ---
It works for LDC, with shared druntime only (i.e., not with static druntime),
because it has proper shared druntime support on Mac too, unlike DMD. It's
using a generalized `rt.sections_elf_shared` in druntime for Mac targets. So
https://github.com/dlang/druntime/pull/2322 would fix this, but needs compiler
support from DMD.
