Unfortunately this problem was still present as of last night, CET time. 
I'm currently trying to run the Borland debugger on 
dominator_tree_test.cpp, but it just crashed on me. I'll try and be more 
careful next time around.

In my opinion we should tackle this problem from two sides: trying to 
avoid such an unwieldy output from this test, but also ensuring that pjl 
  truncates overly long line to a reasonable size. I would venture that 
10KB would be a reasonable size, given how certain compilers fully 
expand some template definitions.

Thoughts?

Cheers,
Nicola
