This is causing nightly servo to crash with hardware acceleration.


  • ./mach build -d does not report any errors
  • ./mach test-tidy does not report any errors
  • These changes work around #19519
  • These changes do not require tests because testing requires AWS instances with GPUs.

This change is Reviewable

I’d like to have something in CI to make sure we don’t regress this again.

@SimonSapin yes, I've been talking to @glennw about at least running a smoke test on Mac to check for this. For Linux, we'd need AWS instances with GPUs.

I’ve edited the PR message so that merging this does not close #19519. This is not a fix, only a temporary work-around. We’ll still need to find and file the compiler bug.

Downgrading Cargo broke some other things :/ #19635

Added a minimal smoke test to one of the mac builders.

Using -o is the case that does not cause #19519’s crash, isn’t it?

@SimonSapin I believe -o doesn't imply -x, and still uses the GPU. The mac builders have GPUs, which is why we can run it there.
