lldb --version
lldb-1205.0.27.3
Apple Swift version 5.4 (swiftlang-1205.0.26.9 clang-1205.0.19.55)

I didn’t install lldb itself, but I assume it was installed together with the Xcode command line tools.

The entitlement seems to be a frequent issue but it is very hard to find in DuckDuckGo.

Except for Emacs exiting without doing anything?
