1570025 - Rust frequently fails with "Compiler not supported"

Status: NEW

(Firefox Build System :: General, defect)

Description

[Dave Townsend [:mossop]]

For the past half week or so periodically, usually during an incremental build, rust will complain that it doesn't support my compiler. It will often do it for many but not all crates. Sometimes rebuilding again works. Sometimes it gets worse.

I filed https://github.com/mozilla/sccache/issues/485 for this, it looks like an issue somewhere in sccache.
