FINAL RESULTS:

data/py3c-1.2/include/py3c/capsulethunk.h:90:5:  [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(name_dup, name, name_length);
data/py3c-1.2/test/test_py3c.c:290:2:  [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 data[200];
data/py3c-1.2/include/py3c/capsulethunk.h:83:27:  [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).
    size_t name_length = (strlen(name) + 1) * sizeof(char);

Not every hit is necessarily a security vulnerability.
There may be other security vulnerabilities; review your code!
