Sorry, ignore my comment: Cython no longer uses PyUnicode_FromString(NULL, 0) in the master branch. The change was backported to the 0.29.x branch, but this stable branch requires a second fix, so I wrote it: https://github.com/cython/cython/pull/3721 Victor Le ven. 3 juil. 2020 à 16:00, Victor Stinner <vstinner@python.org> a écrit :

Of course, there is an API to create an empty string: PyUnicode_New(0, 0); But since Cython is using `PyUnicode_FromString(NULL, 0)`, keep it working for some versions will mitigate the breaking change. Note that we can remove wchar_t cache while keeping it working.
Anyway, this is an idea for mitigation. If all of maintained packages fixes it before Python 3.11, mitigation is not needed.
Can someone propose a Cython PR to use PyUnicode_New(0, 0) on Python 3.3 and newer, or PyUnicode_FromString(NULL, 0) on old Python versions?
