FINAL RESULTS:

data/lola-1.4/calc.c:74:6:  [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.
	    char num_buf[32];
data/lola-1.4/calc.c:38:6:  [1] (buffer) getchar:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	c = getchar();
