Thanks! I forgot that run.dlang.io supports all those old
compilers.

I do it by defining a configuration “build-deps” in my dub.sdl
with target type “none” and then doing the build as two steps
in the dockerfile:

Is there a current "Best Practices" for logging in D?
For the actual logging, I know of `std.experimental.logger`.
However, the `experimental` has kept me away from it.
Is it good, or are there any better alternativ

Also is any file logger thread safe?

I am encountering a strange problem with the GC on a specific

at the first attempt to clear the current memory pool to make
