Richard,
Mark Mitchell has fixed 7086, which is another PR about excessive time
spent in "expand". In this PR the slowdown is not nearly as bad as
yours, so the issues could be unrelated, but maybe you try this once
more with an updated GCC 3.3 tree?
I tried to download your testcase, but the indicated URL
"http://www.tat.physik.uni-tuebingen.de/~rguenth/DynamicLayout2.ii.gz"
does not exist.
