compiler error: cannot relate bound region

[benaryorg]

My nightli.es build of one of my first experiments with rust just panicked when compiling on travis.
log.txt is on Pastebin

The error was that: error: internal compiler error: ../src/librustc/infer/region_inference/mod.rs:734: cannot relate bound region: '_#0r <= ReEarlyBound(TypeSpace, 0, 'r)

Everything should be in that logfile, for convenience, here's the repo.

See #34780 and #34791

I just opened #34839 which was also a duplicate of other issues

Okay, sorry for the duplicate then.
