EventInstance::stop() crashes with callback

FMOD Studio
1

If an EventInstance has a callback that uses EventInstance::release(), fmod will crash on a call to EventInstance::stop(FMOD_STUDIO_STOP_IMMEDIATE).

Here is a simple callback from the examples that just calls EventInstance::release():

FMOD_RESULT F_CALLBACK eventCallback(FMOD_STUDIO_EVENT_CALLBACK_TYPE type, void* parameters)
{
    if (type == FMOD_STUDIO_EVENT_CALLBACK_STOPPED)
    {
        ERRCHECK( ((FMOD::Studio::EventInstance*)parameters)->release() );
    }

    return FMOD_OK;
}

Assuming I have an already created eventInstance, the following code will crash fmod:

ERRCHECK( eventInstance.setCallback(&eventCallback) );
ERRCHECK( eventInstance.stop(FMOD_STUDIO_STOP_IMMEDIATE) );

I am guessing this is because FMOD_STUDIO_STOP_IMMEDIATE releases the event instance internally. Can anybody confirm this? Currently I am working around this by setting the callback to null before I use FMOD_STUDIO_STOP_IMMEDIATE.

Thanks for the report. We have reproduced the crash here and will get this fixed as soon as possible.

This crash has now been fixed for the next release (version 0.01.04).
