FINAL RESULTS:

data/gwaterfall-0.1/src/waterfall.c:124:56:  [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).
  XftTextExtentsUtf8 (GDK_DISPLAY (), theme_font, buf, strlen (buf), &extents);
