Gave it a try and dev-lang/rust:1.83.0 built itself fine for me (had no other rusts on the system to be sure it was used). Maybe related to target-cpu=native? I'm using that as well (RUSTFLAGS="-Ctarget-cpu=native -Cdebuginfo=0" -- when unspecified opt-level defaults to 3 for release profile), but it's a skylake, could potentially be cpu-specific. Been a while afaik, but did happen in the past that it caused problems with rust itself.

"-C target-cpu=native" doesn't cause the build failure when GCC 14 is set as default, removing the flag when building with GCC 15 is also fine. When using GCC 15, using "-C target-cpu=native" for the first build is enough to break the second build even with the flag omitted, so it's getting miscompiled somehow. I can't get a better backtrace, because building with USE=debug makes me run into https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117724
Created attachment 913122 [details] backtrace for rustc_smir The backtraces are over the character limit, so I am going to attach the output

(In reply to Kostadin Shishmanov from comment #3) > "-C target-cpu=native" doesn't cause the build failure when GCC 14 is set as > default I can add that I was indeed using gcc-14.2.1_p20241116, have not tried 15 at the moment.
I decided to do a bisect, though it might not be correct, since the second rust build fails, possibly because it needs another newer commit, but www-client/firefox fails in a similar way, so I used that as a reference instead. https://github.com/rust-lang/rust/commit/5c1c72572479afe98734d5f78fa862abe662c41a ``` From 5c1c72572479afe98734d5f78fa862abe662c41a Mon Sep 17 00:00:00 2001 From: joboet <jonasboettiger@icloud.com> Date: Thu, 15 Aug 2024 13:28:02 +0200 Subject: [PATCH] std: implement the `random` feature Implements the ACP https://github.com/rust-lang/libs-team/issues/393. ``` I tested if rdrand is broken on my CPU with this but it doesn't seem to be the case: https://gist.github.com/andrew-d/bcbe477f7de9a03c7b8285bcee531196 adding `-C target-feature=-rdrand,-rdseed` to RUSTFLAGS was also no luck.
Looks like I made some error in testing, GCC version has no effect on it, it's also reproducible in a clean chroot, where I am building with Clang 18, so it looks like the compiler used is irrelevant.
Time to report upstream if can reproduce manually?
