912304 - Differential Testing: Different output message involving decodeURIComponent

Status: RESOLVED DUPLICATE of bug 911369

(Core :: JavaScript Engine, defect)

Description

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

g = this;
(function() {
    toString = (function() {
        var r = x % 2;
    })
})()
var x = 1;
valueOf = Uint8Array.bind;
try {
    [this].some(decodeURIComponent);
    x = g;
    print(g);
} catch (e) {}
try {
    print(g);
} catch (e) {}

shows nothing on js opt shell on m-c changeset 8c5a94ba1096 without any CLI arguments, when the testcase is passed in as a CLI argument. However it shows only the following with --ion-eager:

undefined

My configure flags are:

 --enable-optimize --disable-debug --enable-profiling --enable-gczeal --enable-debug-symbols --enable-methodjit --enable-type-inference --disable-tests --enable-more-deterministic --enable-threadsafe <more NSPR compilation flags>

Duplicate of bug 911369, verified the patch there fixes it.

Tests that use valueOf are likely duplicates until that bug is fixed :)
