I don't know if this helps anyone, but I added some "pragma(msg, 
__LINE__.stringof);" to "dwt-samples\snippets\treeeditor\Snippet111.d" (the 
one that's hanging), and DMD 1.039 appears to be hanging on this line:

line 102: composite.addListener (DWT.Resize, dgListener( &handleResize, 
composite, text, inset ));
