But the greenlet community is saying this is a gcc bug and it would not be safe to revert the greenlet change that exposed this issue. I have no idea whether that is true or not. Supposedly this should be fixed by https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9213244550335bcb2b8590a0d7d58ac74c932361 but that fix is not present in the latest version of gcc (5.4.0) available for Ubuntu 16.04 LTS.

A debugger is not configured
---Steps to Reproduce---
This should be reproducible with `git clone git://github.com/python-greenlet/greenlet; cd greenlet; python setup.py bdist_wheel`, though it was originally found using pypi rather than github and with a more complicated (scripted) command as detailed in the greenlet bug description.

Opened https:/ /github. com/python- greenlet/ greenlet/ issues/ 136 because attempting to build bdist_wheel for greenlet 0.4.14 on ppc64le Ubuntu 16.04 LTS yields the following error:
