This is clearly a bug.  Can you please run the testcase like this:

opt test.bc -time-passes -track-memory -disable-output


When I run this, it looks like domset and post-dom set take about 21M 
each.  Does it take significantly more memory for you?

In any case, this is a bug and should be improved.  I will look into it 
when I get a chance in a couple of weeks.  That said, please file a 
bugzilla bug for this to ensure I don't lose track of the issue.
