I'm no D expert so I'm not really sure if this is a bug with DCD
or
with the DMD compiler itself? I suspect it might be the later?

I was testing your latest DCD against the Zeus IDE but came across
the following issue when trying to build DCD.

I tried doing the build using the zip files as follows:

1) Download the dmd.2.064.2.zip from here:

http://dlang.org/download.html

2) Download the DCD, DScanner and msgpack source zip files from
these pages:

https://github.com/Hackerpilot/DCD/tree/0.3.0-beta1
https://github.com/Hackerpilot/Dscanner/tree/0.1.0-beta1
https://github.com/msgpack/msgpack-d

When I run the BUILD.BAT the client exe builds just fine but
the build of the server exe hangs.

So I played around with the BUILD.BAT and found the build was
hanging on this file:

dscanner/stdx/d/lexer.d

I then ran this command to just build that one file:

      dmd -v -wi dscanner/stdx/d/lexer.d -Imsgpack-d/src -Idscanner
-O -release -noboundscheck -inline -ofdcd-server.exe

That command gives the compiler trace output shown below.

It appears that the dmd.exe hang on this file with this as the
last
line of trace output:

      TTY_FUNCTION__", "__TIME__", "__TIMESTAMP__", "__traits",
"__vector", "__VENDOR__", "__VERSION__"]).advance

The task manager shows the dmd.exe running but just continually
consuming more and more memory.

Compiler Trace Output

NOTE: Some excessive trace output trimmed with ... characters.
