Description

[Christian Holler (:decoder)]

+++ This bug was initially created as a clone of Bug #758376 +++

The following testcase shows different behavior with options --ion -n -m --ion-eager vs. --no-ion on ionmonkey revision c05b873dad48:


function TEST(section, expected, actual) {}
function TEST_XML(section, expected, actual) {
        return TEST(section, expected, actual.toXMLString());
}
x = new XML("");
TEST_XML(2, "", x);
TEST_XML(3, "", x);


$ debug64/js --ion -n -m --ion-eager test.js
test.js:3: TypeError:  is not a function


$ debug64/js --no-ion test.js
<no output or error>
