digitalmars.D - receiveOnly behavior

This simple program results in segmentation fault. I know i does not 
spawn a thread to receive anything from but is this the expected behavior?

 This simple program results in segmentation fault. I know i does not =

behavior? This was a known issue when calling receive() in the main thread before = ever calling thisTid(). Doing so seemed rather unlikely, but fixing = this was a trivial code change so I've just done so. Expect your sample = to not segfault in the next release.=
