POINTER() saves its result in internal cache. test_pointer_type_name and test_pointer_type_str_name use large names and resulting types consume much memory. This can be one of the causes of tests failure on the AIX buildbot with very limited memory. If run tests repeatedly, the cache grows and can consume all memory even on the machine with enough memory. Proposed patch fixes leaks. |

There is still 32 MB leak in PointersTestCase.test_pointer_type_str_name in test_pointers.py in 2.7. |

I have no ideas how to fix the remained constant memory consumption. But this is 2.7 issue only, so I'm closing this. |
