This is a segfault I am seeing on Python 3.12 related to garbage collection, when trying to do PyJulia work. I also asked Python mailing lists whether there were any changes in the Python GC that might have caused this and will let you know what I find...

Here is my current MWE based on PySR which uses PyJulia:

from pysr import PySRRegressor

model = PySRRegressor()

# This runs fine:
model.fit([[1], [2]], [1, 2])
# ^ This stores some Julia objects (which are PyObject's) into `model.raw_julia_state_`

# This second run starts with `model.raw_julia_state_ = None`, and then re-runs a search
model.fit([[1], [2]], [1, 2])

This immediately triggers a segfault (with no useful printout). This is the smallest MWE I have been able to create thus far. It's difficult to find a pure-Python example of this as the GC behavior seems to be related to long-running jobs (see below).

I also see the issue in my continuous integration tests on Python 3.12 ,over all operating systems, but never before 3.12: MilesCranmer/PySR#450

For example, in one of those segfaults, I see the following backtrace:

Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

It seems like PyCall.jl is trying to free memory via pydecref_ on an object that has already been freed... Could it be that Python 3.12's garbage collection is more aggressive and frees objects before PyCall does?

Additional info dump (updating)

  1. Seems like if I turn off multi-threading, the error goes away.
  2. I ran the serial version through Valgrind.

@stevengj Python 3.12 seems to have slightly changed its garbage collection behavior with python/cpython#97920. I wonder if this is the cause of such issues?

The Garbage Collector now runs only on the eval breaker mechanism of the
Python bytecode evaluation loop instead on object allocations. The GC can
also run when PyErr_CheckSignals is called so C extensions that
need to run for a long time without executing any Python code also have a
chance to execute the GC periodically. (Contributed by Pablo Galindo in
#97922.)

Which julia version are you using?

I am observing random and rare DECREF segfaults using Python 3.10 on julia-1.10.0, but not on 1.9.3.
