cc #55471

A short term solution (really this time! Full fix being grown in #55617) for stack overflows due to deeply recursive syntax trees.

@bors r=me

cc @rust-lang/compiler we want to beta-accept this ASAP, to give people more time to do the actual backport. Beta is being released in Friday, so there isn’t enough time until the meeting.

@oli-obk can you make a PR against beta as well?

Not really, I was only able to hit this issue on travis-CI with the osx_image: xcode6.4 only, and I don't think I can build a toolchain with this PR there and give it a try in the 50 minutes that travis provides time =/

If this fix hits nightly let me know and I can schedule a build of the mach crate to see if the issue is still there.

Maybe we can get it into tomorrow's nightly

Wait, do you mean to ship this in 1.31? The PR for the beta promotion is happening today.

nagisa commented Dec 3, 2018

@pietroalbini yes, it would be great if we could include the beta PR for 1.31 before the promotion happens (or possibly along with the promotion?)

[stable] Add a few critical fixes to the 1.31.0 release

This PR cherry-picks the following PRs to stable:

* #56467: Bump stack size to 32MB
* #56486: Propagate all closure requirements to the caller
* #56519: update edition guide

The changes will be included in the final 1.31.0 binary (to avoid a point release). To deploy the build to dev-static the old manifest needs to be removed from the bucket after the PR is merged.

So I still get a stack overflow using the latest nightly: https://travis-ci.org/gnzlbg/mach/jobs/463833417#L398 - rustc 1.32.0-nightly (b3af092 2018-12-04)

@gnzlbg can you try setting RUST_MIN_STACK=32000000 and run again? That might work as a workaround until we have the proper fix in place
