I think the problem was the excessive use of backtracking when parsing  
ambiguous id-expressions (simple-names vs template-ids).
Now we are doing a better job when parsing those ambiguous names so I  
expect better numbers.

please try again with today's snapshot or pull and recompile the 1.3  
branch (our master branch on gitorious is a bit outdated, it doesn't  
have all the fixes yet).

Thanks for your very detailed report
