Well, libexecinfo is in base now, so I don't see why you're
explicitely disabling it.

The reason why there no core dumps is probably due to the explicit
signal handling for SIGSEGV and friends.  Code that explicitely uses
libexecinfo to show stack traces often don't disarm their signal
handler and then raise() the caught signal.

We could disable that the code that sets up some signal handlers, but
why not just re-enable libexecinfo and see whether it prints a useful
stack trace?
