1066496 - Differential Testing: Different output message involving buildPar

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine: JIT, defect)

Description

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

a = Array.buildPar(6, function(f) {
    {
        function f() {}
        return arguments.callee.arguments
    }
});
print(uneval(a))

$ ./js-dbg-opt-64-dm-nsprBuild-darwin-2db5b64f6d49 --fuzzing-safe --ion-offthread-compile=off testcase.js
[{0:0}, {0:1}, {0:2}, {0:3}, {0:4}, {0:5}]

$ ./js-dbg-opt-64-dm-nsprBuild-darwin-2db5b64f6d49 --fuzzing-safe --ion-offthread-compile=off --no-baseline testcase.js
[{0:function f() {}}, {0:function f() {}}, {0:function f() {}}, {0:function f() {}}, {0:function f() {}}, {0:function f() {}}]

Tested this on m-c rev 2db5b64f6d49.

My configure flags are:

CC="clang -Qunused-arguments" CXX="clang++ -Qunused-arguments" AR=ar sh /Users/skywalker/trees/mozilla-central/js/src/configure --target=x86_64-apple-darwin12.5.0 --enable-debug --enable-optimize --enable-nspr-build --enable-more-deterministic --with-ccache --enable-gczeal --enable-debug-symbols --disable-tests

Jan, any idea what's going on here? This seems to go back beyond Nov 2013 (http://hg.mozilla.org/mozilla-central/rev/df3c2a1e86d3).
