These functions contain '-' in their name; that's a limitation of the
downstream forked patch I applied early to get 4.1.13-6 out the door.
Upstream solved it in a nicer manner, so you can once again have
functions with '-' in the name.  Please try again with the just-released
4.1.14-7.

Having the function wasn't the problem, it was exporting it.  You can
still have the function even in 4.1.13-6, as long as you don't export it.

Umm, that's not good. Can you please come up with a minimal reproduction
formula?  Which program is dumping core? Bash, or something else?  Is it
due to trying to execute the function that was not imported?

Upgrading to the next version :)
