Thanks @messense!

Encountered an exception when using the pyo3 release-0.15 branch: SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats, @davidhewitt do you know why?

Edit: looks like it's not pyo3(cramjam) but zstd package.

[milesgranger]

Yes, zstd is pinned to 1.4.5.1 in benchmark-requirements.txt and I can reproduce locally with Python 3.10

Successfully installed zstd-1.4.5.1

import zstd
zstd.decompress(zstd.compress(b'byes'))
Traceback (most recent call last):

SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

But the latest 1.5.0.2 works fine.

Hit pypa/pip#10151
