Start up tftp and press return, it crashes. Problem fixed in latest version (ftp://ftp.uk.linux.org/pub/linux/Networking/netkit/netkit-tftp-0.17.tar.gz).
Verified with tftp as shipped with i386 7.0. Assigning to developer.
Note: RHL7 doesn't use netkit-tftp but one from hpa.
Ignore my earlier comment -- _tftpd_ is off hpa, tftp itself should be upgraded to 0.17 final.
