I install the latest tortoisehg using pip --user. It is segfaulting (coredumped). However, there is no core. ulimit -c says unlimited. coredumpclt list does not show it (should be python actually)

A standard fedora install these days does all sorts of stuff to intercept core files (which is an incredible pain in the butt when you want to get an actual core file for debugging).
Check the contents of /proc/sys/kernel/core_pattern (and other core_* files in that directory)
You can permanently override this by sticking this line in /etc/sysctl.conf:
kernel.core_pattern = core
Of course there is also the ulimit setting. Regardless of all the /proc/sys stuff, you won't get a core file unless you run the program after setting
ulimit -c unlimited
