hitting assert(0) on mac os

Hey, I'm trying to build a vibe.d app and it crashes here:

We need to know more about what code you are compiling to do anything about it.

[gedaiu]

This is the project that I am trying to build: https://gitlab.com/GISCollective/backend/ogm-server

[kinke]

(Call stack all in the frontend, so most likely an upstream DMD issue.)

[gedaiu]

This is interesting, because the same project builds fine on Linux with the latest DMD and LDC compilers.
