Hello there! What version of Cython are you using? And what Python version?

[ishanSengar]

Hi @MaxHalford thanks for your response, apologies for late reply. I am using Python 3.10.12 and Cython 0.29.32

[MaxHalford]

Ok thanks, I could reproduce the issue. I just pushed a fix, and released v0.0.2.
