Though not as pronounced, definitely significant.

Using binary search I've detected that 30% performance regression of 
cpu2006/437.leslie3d benchmark is caused by revision 117891.

http://gcc.gnu.org/viewcvs?view=rev&revision=117891

I assume same commit causes regression of all other benchmarks from 
cpu2k6 suite (running others to confirm).
