Describe the bug
Memory leak in tcpprep when using regex

To Reproduce
Steps to reproduce the behavior:

  1. ../configure --with-testnic=enp0s5 --with-testnic2=enp0s5 --enable-asan
  2. make
  3. tcpprep -i ../test/test.pcap -o /dev/null -r '96.17.211.*'

Expected behavior
no failed tests

Screenshots
