It's still creating core dumps on my system.  The signal(2) man page
usually lists all of the signals along with the default action if
they're not caught or ignored.  Catching (or ignoring) one signal has no
effect on other signals.  The core(5) man page usually enumerates the
conditions under which core files are and are not generated.  The
abort(3) function usually generates a core file (unless SIGABRT is being
caught or ignored); I don't know of any other common function to do so.
