The repro is:

function ToInteger() {
 if((x === +0)
 || (x === Number.NEGATIVE_INFINITY)){
 }
}
var __v_13 = undefined;
var __v_15 = {};
print("v8-foozzie source: /test262/language/expressions/class/dstr-meth-static-ary-ptrn-elem-ary-empty-init.js");
__v_6 = class {
 static method([[] = function() { __v_15 += 1; return __v_13; }()]) {
 }
};
__v_6.method([]);

... isn't this a duplicate of something...? I don't remember.
