There is a leak (I just marked bpo-42250 as duplicate of this issue):
https://buildbot.python.org/all/#/builders/205/builds/83
OK
......
test_ast leaked [23640, 23636, 23640] references, sum=70916
test_ast leaked [7932, 7930, 7932] memory blocks, sum=23794
1 test failed again:
test_ast
test_subinterpreter() test leaks.
There are two problems:
* _PyAST_Fini() is only called in the main interpreter, I forgot to remove the "if _Py_IsMainInterpreter()"
* _PyAST_Fini() is called after the last GC collection, whereas AST_type contains a reference to itself (as any Python type) in its tp_mro member. A GC collection is required to destroy the type. _PyAST_Fini() must be called before the last GC collection.
