Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

It looks like there is still an open issue for python 3.12: python-trio/trio#2646

The CI error message is a bit opaque, and I haven't had time to dig into it.

I haven't had time to dig into it.

I've published the artifacts which should let us reproduce... if you have a Windows box handy. I do, but just need to find the time to look into it!

This is likely a CFFI problem that we hit before: python-trio/trio#2714 (comment)

You might just double check if import cffi crashes in the test environment, and if so, there's nothing to do but wait for an upstream fix.

Importing doesn't trigger the access violation but loading a DLL does:
