Description Dominique Leuenberger 2016-06-16 13:37:01 UTC 
Since the update to GCC6, openSUSE:Factory/ python3-cffi fails to build
Comment 1 Dominique Leuenberger 2016-06-21 09:23:14 UTC 
Increasing severity - this package has since been promoted to be a ring package (needed by python3-pyOpenSSL and breaks thus now all stagings.
Comment 2 Michal Vyskocil 2016-06-21 20:36:16 UTC 
Added issue upstream:

https://bitbucket.org/cffi/cffi/issues/269/test_verify1py-fails-under-gcc6

The problem is that cffi generates zero shift for global constants, which gcc6 threats as an error. I was not able to understand the cffi code enough to solve it, so hope upstream will help.

I can - as a hotfix - patch this test out.
Comment 3 Michal Vyskocil 2016-06-22 09:51:53 UTC 
OK, I've messed the cffi 1.6 in factory with 1.7 source code yesterday afternoon. That was a reason I was not able to find the responsible line. cffi 1.7 generates | 0, so shall not trigger the error.

I sent update to 1.7 via request 404003
