Examining data/pyrsistent-0.15.5/pvectorcmodule.c

FINAL RESULTS:

data/pyrsistent-0.15.5/pvectorcmodule.c:120:3:  [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(result->items, source->items, sizeof(source->items));
data/pyrsistent-0.15.5/pvectorcmodule.c:563:3:  [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(dest, src, BRANCH_FACTOR * sizeof(void*));
data/pyrsistent-0.15.5/pvectorcmodule.c:758:3:  [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(newVec->tail->items, original->tail->items, TAIL_SIZE(original) * sizeof(void*));
