The xenial upload looks good. I'll be accepting it once I release the
previous python3.5 package that's in -proposed (I'll do that on Monday
since Friday releases to -updates are never a good idea).

Hello Clint, or anyone else affected,

Accepted python3.5 into zesty-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/python3.5/3.5.3-1ubuntu0~17.04.0 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-zesty to verification-done-zesty. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-zesty. In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

This python script reproduces the segfault when run via python3.5

https://bugs.launchpad.net/ubuntu/+source/python3.5/+bug/1711724/+attachment/4934875/+files/bpo-27945.py

** Description changed:

  In certain situations python3.5 will segfault. This bug is confirmed and
  fixed upstream in Python 3.5.4
  
  http://bugs.python.org/issue27945
+ 
+ [Test Case]
+ 1. download attached bpo-27945.py
+ 2. run: python3.5 bpo-27945.py
+ 
+ If it does not segfault, the bug is fixed.
+ 
+ [Regression Potential]
+ The fix has been shown to introduce a minor performance hit for dictionaries 
in general.
