Summary:                    [patch] crash when spying - was working fine in
beta2
Description: 
Didn't think this matched any of the previous app_chanspy bug reports...

I just updated to rc3 last night.  In the course of the morning I
discovered that running ChanSpy on another SIP extension that was bridged
to an IAX2 channel will result in a crash EVERY time.

If I run ChanSpy against a SIP channel that is bridged with another SIP
channel there is no crash.

If I run ChanSpy against an IAX2 channel that is bridged with another IAX2
channel there is no crash.

This behavior was not present in beta2, which was the version I was
previously running.

  were being freed incorrectly.  Under certain conditions this
  resulted in a double free crash.
