Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/libapache2-mod-bw-0.92/mod_bw.c FINAL RESULTS: data/libapache2-mod-bw-0.92/mod_bw.c:148:8: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
