[issue28709] PyStructSequence_NewType is broken; makes GC type without setting Py_TPFLAGS_HEAPTYPE

Josh Rosenberg added the comment: On further checking, looks like there is a lot of work that should be done to initialize heap types (see PyType_FromSpecWithBases) that PyStructSequeuence_Init2 doesn't do (because it thinks it's working on a static type). I think the solution here is

Josh Rosenberg added the comment: Note: Uncommenting the line that forces Py_TPFLAGS_HEAPTYPE isn't enough, since it looks like the PyHeapTypeObject fields aren't initialized properly, causing seg faults if you access, for example, __name__/__qualname__ (or print the type's repr, which
