This line: testPassed(_a + " threw exception " + exception + "."); ends up throwing an exception somehow. Using the function name "valueOf" in the test code is the key to triggering this bug. 28640 1 5729 ggaren 2006-01-16 18:35:11 -0800 Created attachment 5729 Reduction. 82537 2 zwarich 2008-06-07 02:03:07 -0700 This doesn't pass in either Firefox or Opera, for the same reason as WebKit. Are you sure this is a bug? 463177 3 barraclough 2011-09-06 23:07:51 -0700 This test case is invalid, and correctly fails (it fails in firefox, too). The problem is that the test adds a valueOf method to the Object prototype. The test (that an error is thrown) then passes (an error is thrown when Date.prototype.valueOf is applied to a vanilla object). The test harness then tries to format up an error message indicating the test passed, using the following line: testPassed(_a + " threw exception " + exception + "."); This will call ToPrimitive with the numeric hint on exception, which will favor calling the valueOf operator on the object. Since TypeError derive from object, and the object prototype still has the date prototypes valueOf, the ToPrimitive conversion will correctly throw an error. 5729 2006-01-16 18:35:11 -0800 2006-01-16 18:35:11 -0800 Reduction. reduction.html text/html 3080 ggaren PCFET0NUWVBFIEhUTUwgUFVCTElDICItLy9JRVRGLy9EVEQgSFRNTC8vRU4iPgo8aHRtbD4KPGhl YWQ+CjxzY3JpcHQ+CmlmICh3aW5kb3cubGF5b3V0VGVzdENvbnRyb2xsZXIpCiAgICBsYXlvdXRU ZXN0Q29udHJvbGxlci5kdW1wQXNUZXh0KCk7CgpmdW5jdGlvbiBkZXNjcmlwdGlvbihtc2cpCnsK ICAgIGRvY3VtZW50LmdldEVsZW1lbnRCeUlkKCJkZXNjcmlwdGlvbiIpLmlubmVySFRNTCA9ICc8 cD4nICsgbXNnICsgJzwvcD48cD5PbiBzdWNjZXNzLCB5b3Ugd2lsbCBzZWUgYSBzZXJpZXMgb2Yg IjxzcGFuIGNsYXNzPSJwYXNzIj5QQVNTPC9zcGFuPiIgbWVzc2FnZXMsIGZvbGxvd2VkIGJ5ICI8 c3BhbiBjbGFzcz0icGFzcyI+VEVTVCBDT01QTEVURTwvc3Bhbj4iLjwvcD4nOwp9CgpmdW5jdGlv biBkZWJ1Zyhtc2cpCnsKICAgIHZhciBzcGFuID0gZG9jdW1lbnQuY3JlYXRlRWxlbWVudCgic3Bh biIpOwogICAgc3Bhbi5pbm5lckhUTUwgPSBtc2cgKyAnPGJyPic7CiAgICBkb2N1bWVudC5nZXRF bGVtZW50QnlJZCgiY29uc29sZSIpLmFwcGVuZENoaWxkKHNwYW4pOwp9CgpmdW5jdGlvbiB0ZXN0 UGFzc2VkKG1zZykKewogICAgZGVidWcoJzxzcGFuIGNsYXNzPSJwYXNzIj5QQVNTPC9zcGFuPiAn ICsgbXNnICsgJzwvc3Bhbj4nKTsKfQoKZnVuY3Rpb24gdGVzdEZhaWxlZChtc2cpCnsKICAgIGRl YnVnKCc8c3BhbiBjbGFzcz0iZmFpbCI+RkFJTDwvc3Bhbj4gJyArIG1zZyArICc8L3NwYW4+Jyk7 Cn0KCmZ1bmN0aW9uIHNob3VsZEJlKF9hLCBfYikKewogIGlmICh0eXBlb2YgX2EgIT0gInN0cmlu ZyIgfHwgdHlwZW9mIF9iICE9ICJzdHJpbmciKQogICAgZGVidWcoIldBUk46IHNob3VsZEJlKCkg ZXhwZWN0cyBzdHJpbmcgYXJndW1lbnRzIik7CiAgdmFyIGV4Y2VwdGlvbjsKICB2YXIgX2F2Owog IHRyeSB7CiAgICAgX2F2ID0gZXZhbChfYSk7CiAgfSBjYXRjaCAoZSkgewogICAgIGV4Y2VwdGlv biA9IGU7CiAgfQogIHZhciBfYnYgPSBldmFsKF9iKTsKCiAgaWYgKGV4Y2VwdGlvbikKICAgIHRl c3RGYWlsZWQoX2EgKyAiIHNob3VsZCBiZSAiICsgX2J2ICsgIi4gVGhyZXcgZXhjZXB0aW9uICIg KyBleGNlcHRpb24pOwogIGVsc2UgaWYgKF9hdiA9PT0gX2J2KQogICAgdGVzdFBhc3NlZChfYSAr ICIgaXMgIiArIF9iKTsKICBlbHNlCiAgICB0ZXN0RmFpbGVkKF9hICsgIiBzaG91bGQgYmUgIiAr IF9idiArICIuIFdhcyAiICsgX2F2KTsKfQoKZnVuY3Rpb24gc2hvdWxkQmVUcnVlKF9hKSB7IHNo b3VsZEJlKF9hLCAidHJ1ZSIpOyB9CgpmdW5jdGlvbiBzaG91bGRCZUZhbHNlKF9hKSB7IHNob3Vs ZEJlKF9hLCAiZmFsc2UiKTsgfQoKZnVuY3Rpb24gc2hvdWxkQmVOYU4oX2EpCnsKICB2YXIgZXhj ZXB0aW9uOwogIHZhciBfYXY7CiAgdHJ5IHsKICAgICBfYXYgPSBldmFsKF9hKTsKICB9IGNhdGNo IChlKSB7CiAgICAgZXhjZXB0aW9uID0gZTsKICB9CgogIGlmIChleGNlcHRpb24pCiAgICB0ZXN0 RmFpbGVkKF9hICsgIiBzaG91bGQgYmUgTmFOLiBUaHJldyBleGNlcHRpb24gIiArIGV4Y2VwdGlv biArICIuIik7CiAgZWxzZSBpZiAoaXNOYU4oX2F2KSkKICAgIHRlc3RQYXNzZWQoX2EgKyAiIGlz IE5hTi4iKTsKICBlbHNlCiAgICB0ZXN0RmFpbGVkKF9hICsgIiBzaG91bGQgYmUgTmFOLiBXYXMg IiArIF9hdiArICIuIik7Cn0KCgpmdW5jdGlvbiBzaG91bGRCZVVuZGVmaW5lZChfYSkKewogIHZh ciBleGNlcHRpb247CiAgdmFyIF9hdjsKICB0cnkgewogICAgIF9hdiA9IGV2YWwoX2EpOwogIH0g Y2F0Y2ggKGUpIHsKICAgICBleGNlcHRpb24gPSBlOwogIH0KCiAgaWYgKGV4Y2VwdGlvbikKICAg IHRlc3RGYWlsZWQoX2EgKyAiIHNob3VsZCBiZSB1bmRlZmluZWQuIFRocmV3IGV4Y2VwdGlvbiAi ICsgZXhjZXB0aW9uKTsKICBlbHNlIGlmICh0eXBlb2YgX2F2ID09ICJ1bmRlZmluZWQiKQogICAg dGVzdFBhc3NlZChfYSArICIgaXMgdW5kZWZpbmVkLiIpOwogIGVsc2UKICAgIHRlc3RGYWlsZWQo X2EgKyAiIHNob3VsZCBiZSB1bmRlZmluZWQuIFdhcyAiICsgX2F2KTsKfQoKCmZ1bmN0aW9uIHNo b3VsZFRocm93KF9hLCBfZSkKewogIHZhciBleGNlcHRpb247CiAgdmFyIF9hdjsKICB0cnkgewog ICAgIF9hdiA9IGV2YWwoX2EpOwogIH0gY2F0Y2ggKGUpIHsKICAgICBleGNlcHRpb24gPSBlOwog IH0KCiAgdmFyIF9ldjsKICBpZiAoX2UpCiAgICAgIF9ldiA9ICBldmFsKF9lKTsKCiAgaWYgKGV4 Y2VwdGlvbikgewogICAgaWYgKHR5cGVvZiBfZSA9PSAidW5kZWZpbmVkIiB8fCBleGNlcHRpb24g PT0gX2V2KQogICAgICB0ZXN0UGFzc2VkKF9hICsgIiB0aHJldyBleGNlcHRpb24gIiArIGV4Y2Vw dGlvbiArICIuIik7CiAgICBlbHNlCiAgICAgIHRlc3RGYWlsZWQoX2EgKyAiIHNob3VsZCB0aHJv dyBleGNlcHRpb24gIiArIF9lICsgIi4gVGhyZXcgZXhjZXB0aW9uICIgKyBleGNlcHRpb24gKyAi LiIpOwogIH0gZWxzZSBpZiAodHlwZW9mIF9hdiA9PSAidW5kZWZpbmVkIikKICAgIHRlc3RGYWls ZWQoX2EgKyAiIHNob3VsZCB0aHJvdyBleGNlcHRpb24gIiArIF9lICsgIi4gV2FzIHVuZGVmaW5l ZC4iKTsKICBlbHNlCiAgICB0ZXN0RmFpbGVkKF9hICsgIiBzaG91bGQgdGhyb3cgZXhjZXB0aW9u ICIgKyBfZSArICIuIFdhcyAiICsgX2F2ICsgIi4iKTsKfQo8L3NjcmlwdD4KPC9oZWFkPgo8Ym9k eT4KPHAgaWQ9ImRlc2NyaXB0aW9uIj48L3A+CjxkaXYgaWQ9ImNvbnNvbGUiPjwvZGl2PgoKPHNj cmlwdD4KLyogKioqKioqKioqKioqKioqKioqKiBUaGlzIGlzIHRoZSBjb2RlIHRoYXQgdHJpZ2dl cnMgdGhlIGJ1ZyAqLwp2YXIgbyA9IG5ldyBPYmplY3QoKTsKby5fX3Byb3RvX18udmFsdWVPZiA9 IERhdGUucHJvdG90eXBlLnZhbHVlT2Y7CnNob3VsZFRocm93KCJvLl9fcHJvdG9fXy52YWx1ZU9m KCkiKTsKdmFyIHN1Y2Nlc3NmdWxseVBhcnNlZCA9IHRydWU7Cjwvc2NyaXB0PgoKPHNjcmlwdD4K c2hvdWxkQmVUcnVlKCJzdWNjZXNzZnVsbHlQYXJzZWQiKTsKZGVidWcoJzxicj48c3BhbiBjbGFz cz0icGFzcyI+VEVTVCBDT01QTEVURTwvc3Bhbj4nKTsKPC9zY3JpcHQ+CjwvYm9keT4KPC9odG1s Pgo=
