Error(s) that match a know pattern: /var/tmp/portage/dev-python/guppy3-3.1.3/work/guppy3-3.1.3-python3_10/install/usr/lib/python3.10/site-packages/guppy/gsl/../../specs/docexample.gsl does not exist, skipping test /var/tmp/portage/dev-python/guppy3-3.1.3/work/guppy3-3.1.3-python3_11/install/usr/lib/python3.11/site-packages/guppy/gsl/../../specs/docexample.gsl does not exist, skipping test test_classification (guppy.heapy.test.test_Classifiers.ClassificationCase.test_classification) ... python3.11: src/heapy/nodegraph.c:152: NyNodeGraph_AddEdge: Assertion `Py_REFCNT(tgt) < 0xa000000 && (Py_uintptr_t)Py_TYPE(tgt) > 0x1000' failed.
The error is: > python3.11: src/heapy/nodegraph.c:152: NyNodeGraph_AddEdge: Assertion `Py_REFCNT(tgt) < 0xa000000 && (Py_uintptr_t)Py_TYPE(tgt) > 0x1000' failed. This has never been reproduced upstream and shouldn't happen in theory. Is there a way I can maybe get a core dump?
I suspected installing both python 3.10 and 3.11 would cause some sort of conflict leading to this, so I tried that and still could not reproduce.
Was able to reproduce by adding USE=debug on guppy3, and only Python 3.11 is needed.
Root cause is https://github.com/python/cpython/commit/121f1f893a39d0b58d3d2b5597505c154ecaac2a `.ob_refcnt = 999999999` This number is 0x3b9ac9ff, which happens to be larger than the assertion 0xa000000 (7 digits, instead of 8) in: NyNodeGraph_AddEdge: assert(Py_REFCNT(src) < 0xa000000 && (Py_uintptr_t)Py_TYPE(src) > 0x1000); assert(Py_REFCNT(tgt) < 0xa000000 && (Py_uintptr_t)Py_TYPE(tgt) > 0x1000);
