FINAL RESULTS:

data/gtkgl2-2.1.0/examples/lw.c:111:3:  [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 name[LW_MAX_NAME_LEN];
data/gtkgl2-2.1.0/examples/lw.c:217:13:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
  FILE *f = fopen(lw_file, "rb");

data/gtkgl2-2.1.0/examples/zktor.c:670:5:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential

    char s[200];
data/gtkgl2-2.1.0/examples/gdkfont.c:91:17:  [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).
    glCallLists(strlen(fontname), GL_UNSIGNED_BYTE, fontname);
data/gtkgl2-2.1.0/examples/lw.c:40:11:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  int c = fgetc(f);
data/gtkgl2-2.1.0/examples/zktor.c:676:17:  [1] (buffer) strlen:
