3.8 nightly error: TypeError: code() takes at least 14 arguments (13 given)

For a project of mine, I run Travis CI with 3.5, 3.6, 3.7, and nightly. Only nightly is failing with the following error:

@c17r thanks for reporting, someone was seeing a 3.8 nightly failure at the sprint yesterday too. Travis’s allow_failures (just for 3.8 nightly) can be used to prevent the entire build from failing in the meantime in case this is helpful.

I don't think we're constructing code.CodeType any more, please upgrade to the latest werkzeug

I upgraded from 0.15.2 to 0.15.4 and got a new error:

    code = compile(module, "<werkzeug routing>", "exec")

which is #1551 which y'all already fixed for 0.15.5. Good deal.

cheers, sorry for the noise!
