I doubt it. This is a pure performance optimization (reversing some capacity in vectors when we know we're about to append elements to it). It is extremely unlikely to cause such regression.

Does this still reproduce on trunk? Yusuke had introduced a regression with a JSC "bind" patch recently, which impacted reddit.com. He later fixed it on trunk. I am curious if it is the same issue.
