I know you have. The problem is that there might be necessary to do some 
changes to the compiler. That doesn't mean there is a bug.

Yeah, I know. I'm not complaining.

Not 100%. I'm thinking of the __tls_get_addr function which the compiler 
calls:

https://github.com/D-Programming-Language/druntime/blob/master/src/core/thread.d#L4549

That function needs to know which image the given address belongs to. I 
think that the compiler needs to supply that, in addition to the 
address, but I'm not sure. If it does it requires a change in the compiler.

I can add this to bugzilla.

Mac OS X is my main platform. It's natural that I try to get it to work 
there first.
