To answer your questions - Is this signal handler part of a crash reporter - We don't have and crash reporters in our code. If this signal handler isn’t part of a crash reporter? - we don't have any signal handlers in our code We don't have any crash reporters or explicit signal handling code included in our code. We don't really have any idea about the function represented in frame 4 cli_signal_handler where that is implemented or defined, but for sure we don't have that in our project. Is it possible that a third party/vendor framework could have that included? if so what's the way to identify in which framework that the broken implementation has?
