ICE index out of bounds: the len is 1 but the index is 1 #15608
Description
I get an ICE when compiling the lib.rs file here (warning: there's a lot of code).
The code was compiling perfectly, then I added some template parameters to types and traits that are being used almost everywhere, and after updating everything I have this ICE (the diff is here). I don't even know where to start if I had to simplify the case.
error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace

I'm using today's nightly (rustc 0.11.0-nightly (b57d272e9908e164a72bd1a688141031705e1208 2014-07-11 01:11:36 +0000) and I'm on Windows 7.
