N A commented on ASTERISK-30210:
--------------------------------
I guess that's my question then: I have channel A call Wait(1) and channel B call Bridge(${CHANNEL_A}) so that B bridges to A, which is waiting to get bridged by B.
A masquerade happens because Wait will still require a masquerade for the Bridge to succeed. Is there something else I can have channel A do that will not entail a masquerade when B calls Bridge?
I didn't save the exact logs from when this was happening and have since slightly rearchitected some things, though I'd like to switch from ConfBridge back to Bridge so perhaps I can get it to happen again (though I could not just now... for the moment, I'm not getting masquerades that cause the groups to disappear).
However, now and then, I was seeing stuff like this:

What is "Move-swap optimizing Local <-- Local" supposed to mean, other than a local channel optimization?
In this particular case, it did not cause an issue, but when this was causing issues, several of those were happening and it basically pulled the rug out completely from my call, essentially corrupting my state and requiring all channels to manually be hung up, since at that point, those channels would never hang up on their own since the essential state information was lost.
For now I'm a bit hesitant to use Bridge as it seems that, perhaps subject to some race condition, unwanted optimizations can occur, but if there's a way to use Bridge() without triggering one, e.g. like a WaitToBeBridged() for channel A, then maybe that would be more foolproof. ConfBridge() doesn't require a masquerade since each channel is entering a bridge on its own volition, and I'd like to basically emulate that with Bridge.

> A new kind of crash/assertion that I encountered today. Whenever I transfer a call (not using Transfer, this is manually using Wait + Bridge) and a masquerade occurs, Asterisk crashes due to this assertion:
> Looking at the code, this is because AST_CONTROL_MASQUERADE_NOTIFY in func_frame_trace => assert(0);
> I sometimes use FRAME_TRACE for debugging, more so recently, so this might be why I've not seen this before.
> This reproduces consistently.
> I think this assertion is bogus, because if I comment it out in func_frame_trace, nothing happens. No crash, nothing out of the ordinary.
> What's the reason for it? If it's not really good, it should probably be removed, or changed to an error or warning instead of an assert.
