[issue25395] SIGSEGV using json.tool: highly nested OrderedDict

[Martin Panter]

Martin Panter added the comment:

Here is a patch that seems to fix the problem for me. Can someone who knows more about tp_dealloc() methods and the Py_TRASHCAN_SAFE stuff have a look? All I know is that the body of the trashcan stuff can be deferred until an outer nested body is finished, so I though it might be best to defer that PyDict_Type.tp_dealloc() call as well.

Is it worth packaging up my simplified code in a test case, perhaps in an assert_python_ok() child process?
