STINNER Victor added the comment: Well, CPython requires reference counting. This issue looks highly experimental with not activity for 3 years, I close it. -- nosy: +vstinner resolution: -> not a bug stage: needs patch -> resolved status: open -> closed

[issue26891] CPython doesn't work when you disable refcounting

Larry Hastings added the comment: Here is my theory: if the code asserts that it's true, and the code normally runs fine, then it's normally true, and therefore I can remove the assertion and the code will run correctly. I haven't hit that assertion in the peephole optimizer. But I have

Larry Hastings added the comment: I did as you suggested. I also discovered that _Py_NewReference is usually a macro, and I'd only fixed the version in Objects/object.c (the one not being used). When I fixed both those things, and switched the makefile so it uses a different Python

New submission from Larry Hastings: So here's a strange one. I want to do some mysterious experiments with CPython. So I disabled refcount changes in CPython. I changed Py_INCR and Py_DECR so they expand to nothing. I had to change some other macros to match (SETREF, XSETREF, and the
