This is probably caused by the shortcut for multi-branch arms that only looks at the first one, since all variable bindings are shared.

I know about this bug and it has already been fixed (michaelwoerister@78ed2f8#L1R1882) but the fix is not merged yet.

Okay, cool! I am looking forward to having working debug info for Servo, as we have a few new crashes to track down :/

I'll prepare a PR with the fix first thing tomorrow :)
