Describe the bug
Tcprewrite gets stuck in an infinite loop at the while loop at get.c:569.

To Reproduce
Steps to reproduce the behavior:

1. export CC=clang && export CFLAGS="-fsanitize=address -g"
2. ./autogen.sh && ./configure --disable-shared --disable-local-libopts && make clean && make -j8
3. ./src/tcprewrite -o /dev/null -i POC
   The POC file can be downloaded in POC

Expected behavior
The program continues to run for over a week without termination.

System (please complete the following information):

• OS: Ubuntu
• OS version: 16.04, 64 bit
• Tcpreplay Version: 4.4.4

Additional context
After debugging with GDB and adding debug outputs, it seems the program is unable to exit the while loop at get.c:569.
