[New-bugs-announce] [issue43792] "bad argument to internal function" in cython

[Dmitry Marakasov]

New submission from Dmitry Marakasov <amdmi3 at amdmi3.ru>:

I'm playing with adding python3.10a7 port to FreeBSD ports collection, and have run into similar problem with building multiple third party modules (for instance, yaml, yarl and pystemmer). Here's log from yaml:

cythoning yaml/_yaml.pyx to yaml/_yaml.c
