FINAL RESULTS:

data/lua-bit32-5.3.0/c-api/compat-5.2.c:621:5:  [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(newptr, B->ptr, B->nelems);
data/lua-bit32-5.3.0/c-api/compat-5.2.c:632:3:  [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(luaL_prepbuffsize(B, l), s, l);
data/lua-bit32-5.3.0/c-api/compat-5.2.h:132:25:  [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).
  luaL_addlstring(B, s, strlen(s))
