ICE: unstable fingerprints for optimized_mir(rustc_middle) #83817

torhovland · 2021-04-03T17:43:58Z

This is happening when building Rust on WSL2 on Windows. ./x.py build completes successfully, but ./x.py install fails.

My config.toml looks like this:

# Includes one of the default files in src/bootstrap/defaults
profile = "compiler"
changelog-seen = 2

[install]
prefix = "/home/tor/projects/rust/install"

Error output

./x.py install                                                                   Sat 03 Apr 2021 05:05:30 PM UTC

@torhovland as a workaround, you could set incremental = false in config.toml.

torhovland · 2021-04-03T19:00:13Z

@jyn514 Thanks, that works!
