I downloaded python 2.7.6 source and am trying to build with UBSAN flag following the instructions https://devguide.python.org/clang/. But I am getting a lot of misaligned address errors when I run make or make test command. Below is an example:

Objects/listobject.c:161:5: runtime error: member access within misaligned address 0x2adff0773228 for type 'struct (anonymous struct at Include/objimpl.h:253:5)', which requires 16 byte alignment


I need this ubsan enabled python 2.7 as a part of my project.

As Python 2.7 has reached EOL, I'm closing this issue.  However, if you can reproduce the problem with a modern version of Python (3.6-3.8), please reopen it and adjust the versions field appropriately.
