Created attachment 525968 [details] [diff] [review]
Patch

lhs->isTypeKnown() returned true after the call to frame.shimmy, so we did not rejoin from the OOL call to stubs::SetName and marched right into PutActivationObjects.

Ah, noticed this and fixed it in rev dca50d9a5047, we also did the same thing in jsop_getprop (internet blackout since yesterday afternoon, sorry).  I'll add the testcase.
