> func_frame_trace: Channel masquerade triggers assertion
> -------------------------------------------------------
>
> Key: ASTERISK-30210
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-30210
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Core/Bridging, Functions/General
> Affects Versions: 18.14.0
> Reporter: N A
>
> 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.
