I am seeing some failures in travis and some buildbots: 0:02:24 load avg: 3.30 [147/420/1] test_slice crashed (Exit code -6) -- running: test_multiprocessing_spawn (32 sec 523 ms), test_asyncio (45 sec 433 ms), test_multiprocessing_forkserver (47 sec 869 ms) Modules/gcmodule.c:110: gc_decref: Assertion "gc_get_refs(g) > 0" failed: refcount is too small Enable tracemalloc to get the memory block allocation traceback object : <test.test_slice.SliceTest.test_cmp.<locals>.BadCmp object at 0x2ab2051faef0> type : BadCmp refcount: 1 address : 0x2ab2051faef0 Fatal Python error: _PyObject_AssertFailed Current thread 0x00002ab1fe0519c0 (most recent call first): File "/home/travis/build/python/cpython/Lib/test/test_slice.py", line 107 in <lambda> File "/home/travis/build/python/cpython/Lib/unittest/case.py", line 197 in handle File "/home/travis/build/python/cpython/Lib/unittest/case.py", line 782 in assertRaises File "/home/travis/build/python/cpython/Lib/test/test_slice.py", line 107 in test_cmp File "/home/travis/build/python/cpython/Lib/unittest/case.py", line 642 in run File "/home/travis/build/python/cpython/Lib/unittest/case.py", line 702 in __call__ File "/home/travis/build/python/cpython/Lib/unittest/suite.py", line 122 in run File "/home/travis/build/python/cpython/Lib/unittest/suite.py", line 84 in __call__ File "/home/travis/build/python/cpython/Lib/unittest/suite.py", line 122 in run File "/home/travis/build/python/cpython/Lib/unittest/suite.py", line 84 in __call__ File "/home/travis/build/python/cpython/Lib/unittest/suite.py", line 122 in run File "/home/travis/build/python/cpython/Lib/unittest/runner.py", line 176 in run File "/home/travis/build/python/cpython/Lib/test/support/__init__.py", line 1935 in _run_suite File "/home/travis/build/python/cpython/Lib/test/support/__init__.py", line 2031 in run_unittest File "/home/travis/build/python/cpython/Lib/test/libregrtest/runtest.py", line 178 in test_runner File "/home/travis/build/python/cpython/Lib/test/libregrtest/runtest.py", line 182 in runtest_inner File "/home/travis/build/python/cpython/Lib/test/libregrtest/runtest.py", line 127 in runtest File "/home/travis/build/python/cpython/Lib/test/libregrtest/runtest_mp.py", line 68 in run_tests_worker File "/home/travis/build/python/cpython/Lib/test/libregrtest/main.py", line 600 in _main File "/home/travis/build/python/cpython/Lib/test/libregrtest/main.py", line 586 in main File "/home/travis/build/python/cpython/Lib/test/libregrtest/main.py", line 640 in main File "/home/travis/build/python/cpython/Lib/test/regrtest.py", line 46 in _main File "/home/travis/build/python/cpython/Lib/test/regrtest.py", line 50 in <module> File "/home/travis/build/python/cpython/Lib/runpy.py", line 85 in _run_code Usually, this happens with test_slice but when the test runner runs test_slice in isolation, it succeeds. I am afraid that this will be a weird combination of tests. ---------- components: Tests messages: 335185 nosy: pablogsal priority: normal severity: normal status: open title: gc_decref: Assertion "gc_get_refs(g) > 0" failed: refcount is too small versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35961> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
