Zachary Ware  added the comment:

The error message certainly looks more like a compiler bug than a Python bug.  
FTR, we also have several builders on buildbot.python.org [1] running Fedora or 
RHEL on PPC64LE, none of which appear to have a problem.

Anthony Sottile  added the comment:

hmmm strange, the only changes in 3.9.4 are a revert -- perhaps this is a 
flakey bug in gcc and not actionable

I've clicked rebuild on my build, maybe it'll magically fix it

plus xenial is almost end of lifed so I doubt anyone cares about this strange 
architecture on an old platform anyway

[issue43782] Failure to build from source on ppc64le on ubuntu xenial

[Anthony Sottile]

New submission from Anthony Sottile :

I realize this is unlikely to be a helpful report, but something that changed 
between 3.9.3 and 3.9.4 has caused the build to break on (admittedly a strange 
platform) ppc64le


I attached the build log (zipped because otherwise it's too big ?)

The live URL is here: 
https://launchpadlibrarian.net/532585040/buildlog_ubuntu-xenial-ppc64el.python3.9_3.9.4-1+xenial1_BUILDING.txt.gz

Probably the most relevant part of the bug report is this bit, though I'm 
guessing so I don't really know what is useful and what is not.

Preprocessed source stored into /tmp/ccIkITd0.out file, please attach this to
