Dictionary issue on Chrome

[HemingwayGames]

Just letting you know that I've come across an issue with the Dictionary implementation in mscorlib on Chrome. My code has been running fine for the last couple of years, but the issue has started over the last couple of days. I'm not having any issues with Firefox btw.

I'm able to reproduce the error with the following code snippit:

        Dictionary<string, string> dict = new Dictionary<string, string>();
        dict["TickerFPS"] = "1";
        dict["Controller/Event_Tick"] = "2";
        LogDebug(dict["TickerFPS"]);
        LogDebug(dict["Controller/Event_Tick"]);

The last line raises a 'Controller/Event_Tick does not exist' exception.

mscorlib creates the following hashes for the 2 keys: 1932751199 -1497097067

It seems mscorelib _get function is not able to access keys with negative values. hasOwnProperty(hash) returns false for the -1497097067 key.

debugger: this.buckets.hasOwnProperty(-1497097067): false

mscorelib code:

_get: function(key) {
    var hash = this.comparer.getObjectHashCode(key);
if (this.buckets.hasOwnProperty(hash)) {
        ***hasOwnProperty returns false for hash value -1497097067

I'm currently using the following Saltarelle packages: Saltarelle.Compiler.2.6.2 Saltarelle.Runtime.2.6.2 Saltarelle.Web.3.1.0

Thanks,

George

There is also a workaround, see: https://github.com/wordwall/SaltarelleCompiler/commit/470351b98cc9ee1383693b68121fcb2a8a681192
