FINAL RESULTS:
data/fast-cpp-csv-parser-0.0+git20160525~9bf299c/csv.h:66:33: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
mutable char error_message_buffer[512];

around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
