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.
