Fixed In Version: rust-toolset-7-rust-1.24.0-1.el7
Doc Type: Bug Fix
Doc Text:
Cause: Updates to glibc changed the location of thread stack guards. Consequence: Rust threads stopped recognizing faults from stack overflow, causing an abort with a raw SIGSEGV. Fix: Rust's runtime now handles stack guards from glibc in either the old or new locations. Result: Stack overflow in Rust threads is again recognized, printing a message on stderr and aborting with SIGABRT.

'rpmbuild --rebuild rust-toolset-7-rust-1.23.0-2.el7.src.rpm' output on x86_64

Description of problem:

run-pass/out-of-stack.rs testcase is currently failing in rust-toolset-7-rust-1.23.0-2.el7 in both RHEL-7.5 and RHEL-ALT-7.5 on several archs.

This issue was not reproducible in previous rust-toolset-7-rust-1.22.1-1.el7 (https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=632249).

Version-Release number of selected component (if applicable):

rust-toolset-7-rust-1.23.0-2.el7

Steps to Reproduce:

1. rpmbuild --rebuild rust-toolset-7-rust-1.23.0-2.el7.src.rpm
(logs with backtrace are attached)

Additional info:

Running glibc-2.17-221.el7

And this is significant because of the change for bug 1527904.  I think rust-toolset-7-rust-1.22.1 would have failed that test with this glibc too.

I'm already working on this problem upstream on rust#47863.

Actually I was misled by brew build logs :) out-of-stack.rs from rust-toolset-7-rust-1.22.1-1 also failed with the same glibc-2.17-221 (RHEL-7.5-20180125.0 ppc64).

Thanks for pointing this out, Josh.
Comment 3 Josh Stone 2018-02-09 17:29:12 UTC 
The issue is fixed upstream, headed for Rust 1.25 which we'll have for rc/GA.  I'll also backport it to 1.24 so we can verify it in the devtools beta.
Comment 5 Edjunior Barbosa Machado 2018-02-28 15:52:37 UTC 
Verified that out-of-stack.rs testcase no longer fails on rust-toolset-7-rust-1.24.0-1.el7:
