I have received your messages just now.

In lldb's command line:
process handle -p true -s false -n true // otherwise lldb will
Hi Gabriel. Happy that you’re getting some progress. Did Jens’s reply not

it still stops in mach_msg2_trap when I send a SIGUSR1 to my app.
But at least, I get a more meaningful stack trace:
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGUSR1
* frame #0: 0
