Tahoe 26.5.2 Debugging a macOS desktop C++ application on a Mac Mini M1 2020. The application runs under Rosetta2. Once the debugger has hit a breakpoint: Step Over freezes up every single time. Step Into usually works the first two or three times, then freezes. Sometimes Xcode eventually shows an error message saying that it has killed the lldb process. The debug output shows a warning "Unable to obtain a task name port right for pid 428: (os/kern) failure (0x5)". PID 428 is not listed in Activity Monitor. The only way out of this situation appears to be to kill the application. The application runs as expected when there are no breakpoints. I am occasionally getting the error "Debug session ended with code -1: lost connection" I have sent several reports to Apple via the Feedback Assistant.
