ok, it might be an issue with D then.

On compile I print out the pragma then I run the program and it 
writes that same msg to disk... since there is no way to save to 
file at compile time.
What is being printed and what is being written is the same 
string so I know it is the visual that is only incomplete. I 
don't have a simple example right now. The length of output is 
about 50k chars.

For example, the last line of output looks like

....
Add = cast(typeof
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped 
==========

...which changes and that is definitely not the last line of the 
pragma). I'll try to throw together code that demonstrates the 
issue but it might take some time.

It's probably not an issue with visual d then.
