If I am not mistaken, I think that PyStructSequence_NewType() should set the Py_TPFLAGS_HEAPTYPE flag in tp->flags (which it currently does not). The original version initially works fine, but ultimately crashes at exit time in finalization with Fatal Python error: type_traverse() called for non-heap type 'E_FILE' #0 0x00007ffff12913d5 in raise () from /lib64/libc.so.6 #1 0x00007ffff1292858 in abort () from /lib64/libc.so.6 #2 0x00007ffff2360484 in Py_FatalError (msg=<optimized out>) at Python/pythonrun.c:2364 #3 0x00007ffff22e5354 in type_traverse (type=0x10b47a0, visit=0x7ffff2374350 <visit_decref>, arg=0x0) at Objects/typeobject.c:2892 #4 0x00007ffff2374bd1 in subtract_refs (containers=0x7ffff26466c0) at Modules/gcmodule.c:386 #5 collect (n_uncollectable=<synthetic pointer>, n_collected=<synthetic pointer>, generation=2) at Modules/gcmodule.c:891 #6 collect_with_callback (generation=2) at Modules/gcmodule.c:1048 #7 0x00007ffff2375436 in PyGC_Collect () at Modules/gcmodule.c:1476 #8 0x00007ffff235f698 in Py_Finalize () at Python/pythonrun.c:521 #9 0x00007ffff6e70b70 in CSpythonFinalize () at nmds_python.c:44652 #10 0x0000000000407399 in main () Setting the flag manually after creation lets the problem disappear. |

As commented in issue15729, the Py_TPFLAGS_HEAPTYPE flag is now set in PyType_FromSpecWithBases() which is called by PyStructSequence_NewType(). I think this is no longer an issue. |

Thanks @nanjekyejoannah for comment. Yes, I found that the codes are updated. see https://github.com/python/cpython/blob/bd44a7ead9f7336d7bb45f186b2b6ca0300154f7/Objects/structseq.c#L488 I close this issue. |
