The macro Py_UNICODE_COPY was replaced by a function in CPython 3.9, and that function cannot compile with full warnings enabled + warnings as errors under Clang. The problematic line:
Py_DEPRECATED(3.3) static inline void
Py_UNICODE_COPY(Py_UNICODE *target, const Py_UNICODE *source, Py_ssize_t length) {
memcpy(target, source, length * sizeof(Py_UNICODE));
}
has an implicit conversion of Py_ssize_t into size_t, which creates:
/Users/runner/hostedtoolcache/Python/3.9.0-beta.5/x64/include/python3.9/cpython/unicodeobject.h:55:: implicit conversion changes signedness: 'Py_ssize_t' (aka 'long') to 'unsigned long' [-Werror,-Wsign-conversion]
error: implicit conversion changes signedness: 'Py_ssize_t' (aka 'long') to 'unsigned long' [-Werror,-Wsign-conversion]
memcpy(target, source, length * sizeof(Py_UNICODE)); memcpy(target, source, length * sizeof(Py_UNICODE));
An explicit cast to size_t (is there a Py_size_t?) should be made. |
