Description
Minimizing from rustc is pretty impossible, and my attempts so far to deliberately provoke this didn't work. I initially got this error from the bootstrap/beta compiler while compiling rustdoc. This time it randomly happened again, but this time from my dev rustc on stage1 core.
It doesn't occur again after an x.py clean, thus the though that it is incremental metadata related.
