Importing causes python 3.10 to crash

[RyanHope]

I try importing this module and after sitting for a few moments, python closes with no output.

[rkbennett]

Which branch are you using?

[RyanHope]

I'm on the main branch, I didn't notice the branches for specific versions. I will go test 3.10 branch, however, I ideally need to use this on 3.8.

[rkbennett]

I don't currently have one compiled for 3.8, if you put in a request for adding it I can try to put one together when I get back from out of town, but that'll be a couple weeks.

[RyanHope]

Well to be honest, I think I tested this project before I found your other. Loading a python module from mem (compiled or source) is my ultimate goal here so I think I should focus my efforts testing pythonmemimporter and od_import.

[rkbennett]

That's fair, just keep in mind stuff can get finicky, for instance Crypto and Crtyptodome have nonstandard pyds so I had to hook them in od_import. Feel free to close if you feel the issue has been resolved

[rkbennett]

Would you be able to test importing one of your cython pyds with this to see if it works, just for a comparison to pythonmemimporter

[RyanHope]

On my todo list for today.

Tested on 3.11
