FINAL RESULTS:

data/python-multidict-5.0.0/multidict/_multilib/pair_list.h:143:9:  [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(new_pairs, list->buffer, (size_t)list->capacity * sizeof(pair_t));
