FINAL RESULTS:

data/patman-1.2.2+dfsg/prefix_tree.h:32:11:  [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.
	unsigned char drop[5] ;
data/patman-1.2.2+dfsg/prefix_tree.cpp:518:30:  [1] (buffer) mismatch:
  Function does not check the second iterator for over-read conditions
  (CWE-126). This function is often discouraged by most C++ coding standards
  in favor of its safer alternatives provided since C++14. Consider using a
  form of this function that checks the second iterator before potentially
  overflowing it.
