This... looks like a local error? Maybe a malformed RUST_LOG? We're clearly landing PRs so doesn't seem like it's fundamentally broken...

est31 commented 7 years ago

I can reproduce this error when trying to compile stage2 libcore, and am investigating atm what its cause could be.

Note that I can't reproduce it on master, only on a custom branch, so it might be a totally different issue. In any case, the code and backtrace are:

nagisa commented 7 years ago

Can’t reproduce myself anymore. My suspicion is that I had some sort of environmental factors (env-vars) at the time that made this issue surface, but I cannot remember what they might have been. Pretty sure I hadn’t RUST_LOG set or it was empty, though.
