Take a look at that warning message:

Sequence 'TAAGAACAATAAUAACAA' in line 2 has invalid character after 12
+ at parse_dna.pl line 7, <DATA> line 2.
                                 ^^^^^^                               
+                                ^^^^^^

The warn function already includes $. in its output, unless your message ends in "\n".
