EXC_BAD_ACCESS in SocketIOTransportXHR.m

[sjeast]

I'm getting a crash when I try and connect to a very simple test SocketIO server setup to use XHR (as it will run on Heroku). At the moment I'm just testing locally on my Mac and when I try and connect to the server it crashes as line 243 of SocketIOTransport.m:

if (![message isEqualToString:@"1"]) {
    NSArray *messages = [self packetsFromPayload:message];
    [messages enumerateObjectsUsingBlock:^(NSString *message, NSUInteger idx, BOOL *stop) {
        [delegate onData:message];
    }];
}

I downloaded a Zip of the master today which is what I am using in the project so I asume that is the tip revision.

The server code looks like this:

var port = process.env.PORT || 5000;

var express = require('express'); var http = require('http'); var app = express(); var server = http.createServer(app); var io = require('socket.io').listen(server);

app.get('/', function(request, response) { response.send('Running'); });

server.listen(port);

io.configure(function () { io.set("transports", ["xhr-polling"]); io.set("polling duration", 10); });

io.sockets.on('connection', function (socket) { console.log("Connection made"); });

EDIT - adding more info:

I'm running socket.io 0.9.16

here is the output on the server side:

and on the iOS side:
