this is very hard to made a minimal example, and the projects only build with ldc.

There is a struct TcpServer has no destructor, and all method is @nogc nothrow.

but some how when I use it on function run @nogc nothrow, ldc report : @nogc function run cannot call non-@nogc destructor TcpServer.~this


this problem only exists for this TcpServer struct, all other struct without ~this() is ok.

And the code run fun before we add copyConstructor, but this one has no copyConstructor.

Then just add destructor with @nogc attribute.

It is also possible a member of the struct has a destructor that is triggering it.

Thanks, I check all member and one of them is not @nogc nothrow. add @nogc nothrow to member fix it.
