jl.PythonCall.JlWrap.Cjl._pyjlbase_name crash in Python 3.13 #620
Description
Affects: JuliaCall
Describe the bug
Just accessing juliacall.Main.PythonCall.JlWrap.Cjl._pyjlbase_name crashes python 3.13.3. It doesn't crash python 3.12.
I know it's a private field, but what I actually wanted to do was juliacall.Base.summarysize(juliacall.PythonCall) which crashes due to _pyjlbase_name
from juliacall import Main as jl
jl.PythonCall.JlWrap.Cjl._pyjlbase_name

I tried to patch it with
jl.Base.setglobal_b(jl.PythonCall.JlWrap.Cjl, jl.Symbol("_pyjlbase_name"), "juliacall.ValueBase"), but I get "invalid redefinition of constant Cjl._pyjlbase_name".cjdoris commentedon Aug 30, 2025
I think this was another symptom of a bug that was recently fixed - can you try again on latest PythonCall?
