The reason is because of the fix for > https://issues.dlang.org/show_bug.cgi?id=22515.

Fix Array to cast away the shared when using these functions (a > reasonable assumption) >From my perspective, it should be illegal to cast away the sharedness if an aggregate was defined `shared struct/class T` (this could be extended to any type qualifier, but let's just stick to shared). If the user opted to define the aggregate as such, I think it is reasonable to assume that any use of such an object is going to violate the definition of the object. > 2. Fix the druntime functions so they also accept `shared` pointers In my opinion, this is the most sensible approach. > 3. close this bug as wontfix, and I'll have to work around it in the project > I'm trying to compile (libasync) --
