FINAL RESULTS:

data/slcfitsio-0.3.8+nosvn/src/cfitsio-module.c:817:4:  [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.
