When I try to build it on Windows 10, LDC begins to eat a lot of memory (load ~ 95 - 100%) and after some time Windows freezes - hard reboot is needed to reset.

On run.dlang.io I get "server error".

My LDC: 1.24.0-beta1 (DMD v2.094.0, LLVM 11.0.0)

Have you run that with dmd as well?

I don't have DMD on local computer.
But on run.dlang.io with DMD I also get server error.

I can reproduce this with DMD 2.094.0 on macOS as well. Seems to be a frontend issue. Some infinite recursion. You're probably running out of memory. For me the process is killed after consuming over 22 GB out of my 16 GB :). I've reported the issue here [1].
