Just double checked, this actually happens on my development (x86_64) laptop! I think it's because the only option for a trap on this platform is 0xcc or something, I haven't looked in great detail, but ultimately without this line, the test fails on x86.

OK I did a quick check on Compiler Explorer - `__builtin_debugtrap()` is `int3`, but `__builtin_trap()` is `ud2`, which simply aborts the process. I don't think there's anything that lldb should be doing differently here, I think it's ok to say that some platforms might have exited here but we should check for correctness if they're still running.
