FINAL RESULTS:

data/tideways-5.0.2/tracing.c:208:5:  [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 symbol[512] = "";
data/tideways-5.0.2/tideways_xhprof.c:115:34:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    return php_output_write(str, strlen(str));
