Comment 23 for bug 2002043

Thanks for providing the workarounds. While the workarounds work in cases when user is willing to compile extensions from the python package sources and aware of these problems, for the most common cases work arounds are not feasible. There are 100’s of python packages with extension modules and the most common use case is to install them using pip. The general expectation from end user is to have them compile with right flags and work without any extra work. So it’s going to be very challenging for us to communicate end users about this potential problem which only occurs with Python 2 on Ubuntu distributions.
I’m also not clear about the regression problem mentioned above. Why would we expect regressions if the patch itself is trying to fix the bug and use right optimizations (in this case O2)?
