Random Crash on Call Termination in Conference Calls (Linphone SDK v5.3.80+)

[Mahe2027]

Hi Linphone Development Team,

I am encountering a crash with Linphone SDK version 5.3.80+ when terminating a call, especially during conference calls. The crash does not occur every time but happens randomly. Below are the details of the bug:

1. Describe the bug:

The crash happens intermittently, particularly when terminating a call in a conference call scenario. The error message generated is: Pure virtual function called!

This issue occurs only in versions 5.3.80 and above, while versions 5.3.76 to 5.3.79 work as expected without crashes.

I am using the Linphone SDK via the Maven repository.
2. To Reproduce:

Join or create a conference call using Linphone SDK (version 5.3.80 or later).
Terminate a call within the conference (the crash happens randomly).
Observe the crash.

3. Expected behavior:

The call should be terminated successfully without causing a crash, even during conference calls.
4. Please complete the following information:

OS: Android 11
Version of the App: Using In our custom app
Version of the SDK: 5.3.80+
Where you got it from: Linphone Maven Repository

8. Additional context:

The crash is intermittent, and it seems to occur more frequently during conference calls. The issue appears only in versions 5.3.80 and above, and versions 5.3.76 to 5.3.79 do not exhibit this behavior.

Hi @Mahe2027,

Please attach logs from the start of the call to the moment it crashes please.
