Description
I've pushed a commit to this branch of the time repository, containing the full code that causes the error. I haven't yet tried to create a minimal example; I can do that at some point if it's desired.
This code does not have any issue running cargo check on rustc 1.41.0. It fails on 1.41.1.
Output with RUST_BACKTRACE=1:
error: internal compiler error: src/librustc/dep_graph/graph.rs:680: DepNode Hir(time[a7e0]::format[0]::parse[0]::parse[0]::{{misc}}[1]::{{misc}}[0]) should have been pre-allocated but wasn't.

Looks like there are a number of issues possibly related. Feel free to close if it's a duplicate, of course.
