[cfe-commits] [PATCH 1/4] [clang.py] Store reference to TranslationUnit in Cursor and Type

[Gregory Szorc]

This patch stores a reference to the underlying TranslationUnit in
Cursor and Type instances. We want to keep this reference so garbage
collection doesn't collect the TranslationUnit instance, which would
free the backing memory and possibly cause a segfault if the Cursor or
Type instance makes a C API call against a dead TU.

Other types in the module (like File) also need this treatment. Those
will be addressed in a later patch.
