FINAL RESULTS:

data/r-cran-purrrlyr-0.0.6/src/fast-copy.cpp:66:5:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
    memcpy((char*) ACCESSOR(to) + offset_to * sizeof(C_TYPE),     \
data/r-cran-purrrlyr-0.0.6/src/vector.c:45:3:  [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 buf[100];

data/r-cran-purrrlyr-0.0.6/src/utils.cpp:132:24:  [1] (buffer) equal:
  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.
