Yes, I think Walter knows about that.   This is not that.

The difference is this hang is quite deterministic.

I think the line Nick posted is gonna help Walter crack this, though:

That dgListener is a fairly funky little bit of template magic.  And I use it in my program that hangs, on compilation also.

I'm getting the same results as you for both "tree\Snippet15.d" and "treeeditor\Snippet111.d". Both compile fine in just over 30 sec on 1.037. On 1.039 "tree\Snippet15.d" fails after about 30 sec with the same link error I posted above, and "treeeditor\Snippet111.d" goes on for at least 10 minutes (that's when I killed it). 

Can you try cutting down the size of that example until you find the trigger for the long times?

The following is about the best I could do. Unfortunately, I wasn't able to eliminate Tango or DWT from the test case. Maybe someone with more experience in the DWT codebase could improve on this test case.

--------------------
module test;

import tango.core.Traits;
import dwt.graphics.Path;

class Foo(Dg)
{
    alias ParameterTupleOf!(Dg) DgArgs;
}


void main ()
{
    pragma(msg, __LINE__.stringof);
    new Foo!( void delegate() )( );
    pragma(msg, __LINE__.stringof);
}
--------------------

I have Tango 0.99.7, DSSS 0.76, and DWT 3.4-1.

I compiled with:
rebuild -C-v test

The relevant output for DMD 1.037 was:
--------------------
{...trimmed...}
semantic3 test
13L
{no noticable pause}
15L
semantic3 Traits
{...trimmed...}
{no linker error}
--------------------

The relevant output for DMD 1.039 was:
--------------------
{...trimmed...}
semantic3 test
13L
{pauses here for about 1 minute}
15L
semantic3 Traits
{...trimmed...}
OPTLINK (R) for Win32 Release 8.00.1

Error 1: Previous Definition Different :
_D5tango4text4Text11__T4TextTaZ4Text4Span6__initZ
--- errorlevel 1
--------------------

Also, there seems to be some sort of cumulative effect going on. I noticed that the more I trimmed from the test case, the less pause there was in DMD 1.039. With the original "dwt-samples\snippets\treeeditor\Snippet111.d" the pause was more than 15 minutes (I killed it after that). In the above code, it's only about 1 minute. But in either case, there was no noticeable pause in DMD 1.037.

Thanks, can you add this to bugzilla?
