###### Version safari 16.3 (18614.4.6.1.6) ###### Test case ```js function foo() { var obj = {}; var p0,p1 switch (p0) { case (p0 = NaN): case p1: obj.prop = NaN; break; } return obj.prop }; print(foo()) ``` ###### Execution steps .jsc Testcase.js ###### Output ``` undefined ``` ###### Expected result NaN ###### Description The correct output of the test case should be `NaN` while javascriptcore yields `undefined` . I think it might be an issue of javascriptcore.
