Yes, thank you. Seems the bug is in DFG, with the eager compilation parameters some optimization pass must be triggered that generates slightly different (and buggy) DFG code. Almost all of it is identical though, so hopefully it won't be that hard to narrow it down.

(Also, I guess that means the bug probably is in the parts of the bytecode index patch that touch DFG classes)
