Just in case: turning of the collector for variable d doesn't make a
difference. Stil crashes.
The interesting part of the stack trace is:
<something that tries to send an objc message>
#1 0x90a2f337 in _pixelBufferReleaseCallback ()
#2 0x93079d78 in CVPixelBufferBacking::finalize ()
#3 0x9307242e in CVPixelBuffer::finalize ()
That has the *appearance* of CVPixelBufferBacking violating the
finalize rules -- it looks like it's sending a message to the object
that allocated it, but that object has already been garbage collected
out of existence (or, in the case of the second stack trace, been
reallocated already as a different kind of object). If that's so, I
agree it looks like a frameworks bug.
