Details

(Keywords: assertion, testcase)

The following code asserts on TI tip (run with -m -n -a), tested on 64 bit:

this.__defineGetter__("x", gc);
x.__proto__ = this;
__proto__ = 44;
JSOP_SETGNAME could walk different compilation paths when assigning __proto__, depending on whether the global object's properties are unknown. This changes things so that we always walk the same path (and don't need the rejoin hooks).
