I'm also getting this in the output:

Since "perldoc" and related code is written in perl, you can use a debugger to
debug it. You can do:
perl -d `which perldoc` -f sort
See:
* http://perl-begin.org/topics/debugging/
Moreover, can you share some details about your system, its versions, and
the perl version you're using?
