    Hi,

    I am doing loading of images inside a screen, but the user can always navigate to another level even if the image is still loading.
    The monobehaviour initiate the loading of the image and have another coroutine with a yield (www loading routine) statement and displays the image after it's loaded, and this flow works correctly.
    When navigating to another level that monobehaviour just call StopAllCoroutines in OnDestroy, but the crash always happen even if I remove the OnDestroy.
    This doesn't cause problems in the editor or other platforms, but it almost always gives me the following error in webgl in both firefox and chrome.

    I am using unity 5.1.1p3

    Any help is greatly appreciated.

    Could you try to grab the callstack again, this time using a Development build ?

    Pretty sure this bug exists even as of 5.2f2--loading a new level with a pending WWW causes a crash.

    Will isolate into a repro when I get a sec...

    I have been investigating a crash with a similar callstack. In that case, the http request onload callback is called after the WWW object has been Disposed.

    Do you have a project i can look at ?
