[crashtracker] Retrieve panic message when crashing #1361

gleocadie · 2025-11-21T13:39:34Z

What does this PR do?

This PR add the panic message to the crash report.

Motivation

In a panic=abort mode, when a process panics, a SIGABORT signal is sent. The crashtracker intercepts the signal, generates a crash report, creates a message based on the signal info and send the report.

Adding the panic message, we can enrich the crash report and help in tracking the crash location.

We take care when the message type is &str, String or unknown.

I added bin_tests tests to check different type of messages and also the fork case.

Additional Notes

For now, we only handle the case of panic=abort, in case of a panic=unwind, the signal handler is not called and we do not generate a crash report.
