vsk added a comment. The issue is that InitLLVM initializes its private PrettyStackPrinter before installing the one-shot default SIGPIPE handler: the PrettyStackPrinter itself eventually calls RegisterHandlers(), which runs before the SIGPIPE handler is installed and therefore doesn't register a SIGPIPE handler.
Why doesn't RegisterHandlers simply unconditionally install llvm's "SignalHandler" as a handler for SIGPIPE? We found that it broke lldb's ability to ignore SIGPIPE, as RegisterHandlers is called by a ton of library code (including library code called by lldb!). I'll be the first to admit that this one-shot sigpipe handler business is incredibly fragile, but unfortunately I don't have a better solution :/.
