Your code as supplied works for me in that it produces the output which I believe you were expecting:

$ perl cctrap.pl 
Term::ReadLine::Stub
try CTRL-C in some text here :abcd^C
 caught CODE(0x194e9a0)INT
xyz
$

The input sequence is: abcd^Cxyz<RETURN>

This runs with perl v5.20.3 and Term::ReadLine 1.14 from bash on Linux. Maybe you just need to avoid Term::ReadLine::Gnu?
