seems to be a problem with the guard.

run attached app (click button on page1, then click row on table\nview, close modal, repeat -> crash)

Claimed from Blain. My previous description of the bug was\nerroneous.

This appears to be a much more serious issue. Stack traces\nindicate the following:

\n

Creation: (count = 1)
\n0: -[TiMediaAudioSession startAudioSession]
\n1: -[TiMediaAudioPlayerProxy initWithProperties:]
\n2: -[TiProxy initWithPageContext:args:]
\n3: -[TiModule createProxy:forName:context:]

\n

With the following when the tab (NOT the modal window!) are\nclosed:

\n

Destruction:

\n

Once for context destruction: (count = 0)
\n1: -[TiMediaAudioSession stopAudioSession]
\n2: -[TiMediaAudioPlayerProxy _destroy]
\n3: -[TiProxy contextShutdown:]

\n

And once for the proxy destruction: (count = -1)

\n

1: -[TiMediaAudioSession stopAudioSession]
\n2: -[TiMediaAudioPlayerProxy _destroy]
\n3: -[TiProxy dealloc]

\n

The solution is to perform a sanity check on (count), but please\nbe aware of the larger issue: All destroy functions MUST\nRELEASE_TO_NIL() all variables and/or perform operations which are\nguaranteed to have NO side-effects in other classes (in this case,\nTiMediaAudioPlayerProxy calls a function with a side-effect in\nanother class: TiMediaAudioSession.) If they must call functions\nwith side-effects, there should be a 'BOOL destroyed' variable\nwhich tracks whether or not the object has already been destroyed.\n(ED'S NOTE: Calling [super destroy] in the appropriate place\nhandles this already; ignore my advice.)

\n

Strongly recommend that this variable (and a sanity check\nassociated with it) be added to TiProxy.

Well I'll be - there's already this variable (and an associated\nsanity check!) in _destroy for TiProxy.

\n

The problem was that [super _destroy] was not called. Fixed.
