ICE 'Box<Any>', /Users/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-mac/build/src/librustc_trans/back/write.rs:56' if incremental build is enabled on macOS Sierra.

[tetsuharuohzeki]

Environment

• OS: macOS Sierra (10.12.3)
• rustc: rustc 1.17.0-nightly (ea7a6486a 2017-02-04)
• cargo: cargo 0.17.0-nightly (385e243 2017-01-27)
• Target code base: Servo (servo/servo@cd63f1b)

Tracking issue on Servo side.

• Fails to build style crate if incremental builds is enabled on macOS Sierra servo/servo#15391

Step to Reproduce

• Try to build servo's repository (./mach build --dev --verbose)
• This problem is reproducible on both cases:
  • Full build.
  • Complete to build once on non-incremental build, and edit some files under /component/style/.

Actual Result

The following error is caused:

This is likely related to too many LLVM threads being open and trying to write out object files at the same time: #39280

A quick fix would be to just limit the number of LLVM threads. I'll look into that.

[nikomatsakis]

Possibly fixed by #39583 having landed. Can you retest?

[michaelwoerister]

Since we have not had any similar reports in a while, I'm considering this fixed. Please re-open if that's not true.
