I don't really know where to start minimizing this thing. The code is a nasty beast and not everything in the repository compiles right now (I'm currently struggling with HRTBs in there and such). Anyway:

  • Clone the https://github.com/vorner/spirit repository
  • Check out the commit 0ce253e4ec35a8accaf4924f17180cd0a9696e78
  • Run cargo +nightly-2019-01-07 run --package spirit-reqwest --example make_request
  • The following ICE falls out:
error: internal compiler error: src/librustc_mir/monomorphize/collector.rs:747: Cannot create local mono-item for DefId(21/0:300 ~ config[6427]::file[0]::{{impl}}[0]::from_str[0])

This seems to have disappeared on the newest nightly (it now compiles fine and runs). So let's close this and thanks :-) (if anyone has an idea what happened here, where it got fixed or has a shorter example that can be put into a test, that would still be nice)

This ICE is back on rustc 1.43.0-nightly (96bb8b31c 2020-03-05) it seems.

Clone this commit of noria and run

$ cargo b -p noria-server

(it takes a while)

You'll then end up with:

error: internal compiler error: src/librustc_mir/monomorphize/collector.rs:745: cannot create local mono-item for DefId(27:436 ~ noria[a50e]::view[0]::results[0]::{{impl}}[0]::new[0])
