Carbon help

I'm trying to develop a class to ease input from data fields in a carbon NIB reference.

I set up the constructor, and everything worked perfectly.

When I tried to add a method to read input from a text field, I started getting errors.

The thing compiles, but the application shuts down and exits "with signal 6, SIGABRT"

here's the code:

                return CFSTR("void");

Any ideas?

c'mon now...someone has to know carbon
