Currently ldc 1.16.0 isn't supported. You can downgrade to ldc 
1.15.0

Have you tried the github issues? I remember dukc having the same 
issue on windows as well.

No you cannot use the concat operator (~). Neither can you use 
new, class, AA or dynamic arrays among others. This is because 
Spasm uses betterC, and a lot of D features aren't available in 
betterC. I am working on a PR for druntime to at least compile to 
wasm without betterC. This will open the way to incrementally 
support more and more D features.

In the meantime you need to get familiar with the betterC 
constraints. You can always look in the examples for workable 
code. Make sure to use the 0.1.13 tag, since master has some new 
unreleased stuff (which I hope to release in the coming month).

There is a string builder in spasm as well as a betterC version 
of the phobos `text` function.

The GC allocator is still unreleased and experimental.
