Comment 1 Miro Hrončok 2021-01-18 11:01:55 UTC 
According to Koschei, this only happens on x86_64 and started with an GCC upgrade :(
Comment 2 Lumír Balhar 2021-01-20 09:17:31 UTC 
I've tried to investigate it and filled: https://foss.heptapod.net/pypy/cffi/-/issues/486

It seems to me, that we can temporarily fix it if we disable compiler optimizations. How bad the idea is?
Comment 3 Lumír Balhar 2021-01-20 09:28:59 UTC 
With `CFLAGS="-O0 -g" CXXFLAGS="-O0 -g" %py3_build` the package builds fine if we really need to build it quickly and unblock others.
Comment 4 Tomáš Hrnčiar 2021-01-20 09:44:58 UTC 
Thank you for having a look at it Lumír. It doesn't block any other packages so I think we can wait for upstream.
Comment 5 Miro Hrončok 2021-01-20 10:14:25 UTC 
gcc 11.0.0-0.15.fc34 fixed this. let's call it a temporary gcc bug.

Lumír, please close the upstream issue.
Comment 6 Miro Hrončok 2021-01-20 10:15:24 UTC 
> Lumír, please close the upstream issue.

I was able to do it myself.
