On Linux x86_64 (2.6.32-300.3.1.el6uek.x86_64 #1 SMP), using the following html application:

<!doctype html>
<html>
    <head>
        <title>My simple App</title>
        <script src='angular.js'></script>
        <script>
        <!--
            angular.module('xApplication', [ ])
            .controller('applicationController', function ($rootScope) {});
         -->
        </script>
    </head>
    <body ng-app='xApplication' ng-controller="applicationController">
    </body>
</html>

and following protractor test (using protractor 0.16.1, with hotfix from angular/protractor#85).

describe('crashcheck', function() {
    'use strict';
    it('should not crash', function() {
        var ptor = protractor.getInstance();
        ptor.get('/');
        ptor.get('/');
        ptor.get('/');
        ptor.get('/');
        ptor.get('/');
        ptor.get('/');
    });
});

Crashes reliably with the following stack trace in phantomjs, built from latest source (also crashes with 1.9.x). Crashes consistently when using maven jetty web server, much less frequently when using 'grunt-contrib-connect' as the server:

With only two 'ptor.get' calls in the test it passes ok, any more than two causes the crash. Seems somewhat related to the report at: detro/ghostdriver#103

When using the original protractor (no modifications) the 'page unload event' error occurs. Crashes in phantomjs still occur under these conditions with the following stack trace:

Using the following protractor config file (with selenium 2.39):

exports.config = {
    seleniumServerJar: process.env.SELENIUM_HOME + '/selenium-server-standalone-2.39.0.jar',
    seleniumPort: null,
    chromeDriver: null,
    seleniumArgs: [],
    sauceUser: null,
    sauceKey: null,
    seleniumAddress: null,
    specs: [
        'test.spec.js',
    ],
    capabilities: {
        'browserName': 'phantomjs'
    },
    jasmineNodeOpts: {
        defaultTimeoutInterval: 10000
    },
    baseUrl: 'http://localhost:8081/'
};

(note that removing the 'defaultTimeoutInterval' occasionally allows the tests to pass crash free, but they usually timeout instead)

It's worth pointing out that using 'browser.driver.get' instead of 'ptor.get' works fine. So I believe it is the 'async script execute' that protractor is doing during it's 'get' (or the script injection) that is triggering the problem. Timing seems to be related - using a slower server (i.e grunt-contrib-connect) fails less often than a faster server such as jetty which fails every time.

Please upgrade to PhantomJS 2. 1.9.x is no longer supported, and known to have many crasher bugs that are fixed in 2 version.
