If it is GC related, then perhaps just the fewer stmts make a latent bug
reproduceable.
As switch conversion is early optimization pass, you could try to binary search
in between the *.o files to see on which the switchconv changes trigger it and
with preprocessed source for that I could double check if switchconv is
correct.

I don't have SPEC2k6 easily available for trying to reproduce this myself
though.
