Stacktrace of exception thrown in workers is not logged

[vfsoraki]

When an exception is thrown in worker, only the message and code of exception is logged.

A stacktrace is logged, but it is the stacktrace of Process and its state, not the actual stacktrace of exception.

Example:

[2021-02-02T14:15:37.836279+00:00] cluster-86033.error: Worker 2 failed: Amp\Parallel\Sync\ContextPanicError: Uncaught Error in child process or thread with message "Call to a member function get() on null" and code "0"; use Amp\Parallel\Sync\ContextPanicError::getOriginalTrace() for the stack trace in the child process or thread in /<project-path>/vendor/amphp/parallel/lib/Sync/ExitFailure.php:46

This exception causes my workers to die (not a bug with Cluster, bug from my code). But logged error does not help at all. I had to to the classical dump&die starting from worker script to find out where was the error.

Is this expected behavior? Am I missing something?

My worker code is pretty much like HTTP server example from this repo.

I'm willing to look into it, if this is an issue.

As a note, the bug in my code happened before loop is actually started.

Maybe that is the reason the exception is not logged properly.
