Research direction

Start with test/back_reference.cpp around line 102 and reproduce its compilation under C++17 and C++20. Trace the std::auto_ptr usage and check the surrounding Boost.Python code for the compatibility boundary; done means the test compiles successfully under both standards.

Written by the indexing model from the issue text.

Description

Fail to compile test/back_reference.cpp with C++20 since std::auto_ptr is removed in c++17.
