rare ijl_bounds_error_int with Julia 1.11 & python 3.13

Beginne mit dem gemeldeten Absturz unter Julia 1.11.6 und Python 3.13.5 und konzentriere dich auf PythonCall's src/JlWrap/C.jl:35, src/GC/GC.jl:99 und src/Core/Py.jl:27 aus dem Stacktrace. Versuche, einen reproduzierbaren BoundsError oder segmentation fault während der Finalisierung zu erzeugen; abgeschlossen ist die Aufgabe, wenn der Fehler erklärt und das betroffene Verhalten ohne Regression korrigiert ist.

Affects: JuliaCall

Describe the bug
Very rarely, my python application crashes while juliacall is invoking a julia function.

This is the error I get:

error in running finalizer: BoundsError(a=MemoryRef(offset=0, ptr_or_offset=0x5a44f85dd300, mem=Memory{Int64}(1819, 0x5a44f85dd300)[....]
