I don't know what you're doing, and maybe __gshared is the

you should be using shared, and using __gshared is risking bugs
precisely because it is not considered part of the type and
does not prevent you from using it a thread-local context. The
compiler will treat it as thread-local, risking subtle bugs
that shared would catch.

I was under the impression that with shared you have to either
a) atomically load it or
b) cast away shared before loading it.
As explained in
https://github.com/ldc-developers/druntime/pull/114#discussion_r161472745 that would very much add boilerplate to its most frequent use case.
