You may be doing something wrong in the code you're not showing us. This works on my machine: 

use strict;
use warnings;

$SIG{INT} = sub { print "caught SIGINT\n"; exit };

sleep 1;
exec $^X, $0;

When I run this, wait a few seconds and send press Ctrl+C I get the "caught SIGINT" message, so the re-installing of the signal handler worked.
