+Subject: [PATCH] python: Avoid a crash on 64-bit systems
+
+Annotate the return type of px_proxy_factory_new() to be void *, as otherwise
+int is assumed. This works fine on 32-bit systems, where void * and int are the
+same width, but is invalid on 64-bit (Linux) systems.
+
+Additionally, annotate the argument type of free() and px_proxy_factory_free()
+to be void * to match.
