I can confirm that.
I presume that this is a serious regression since it involves
optimization?
Which component should I post it against?
Probably against tree-optimization. If later analysis determines that
it is something else, people will reassign it.
This one probably calls for bisection.

Paul, thanks for catching this!
@Richard: Is there a possibility of doing regular Polyhedron runs
at Suse in addition to the SPEC runs? This could also be interesting.
Best regards
Thomas
