I'm not familiar enough with the ngircd codebase, so I am not entirely
sure if `Client` is the right variable to pass to `KillClient` or if
it should be `c` instead.
This crash was found using American Fuzzy Lop.
Build flags:
./configure --without-syslog --with-iconv CC=afl-clang
Run mode:
ngircd -n -f src/testsuite/ngircd-test1.conf
