The same happens with rust 1.49.

This is now a critical bug, because there is no cargo/rust in Tumbleweed for armv7 anymore, which means no mozjs78, so all desktops are broken (X11, Enlightenment, LXQT, etc.)

If I build locally with '-j1' to use only one core, I fail later with:

I'm testing in OBS if this happens with bundled llvm now on 1.49. 


Can you also check a hello world or similar with the upstream toolchains? This way we know that it's not an upstream issue but an issue specific to our build process. You may also need gcc installed already as a linker.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain none

source $HOME/.cargo/env

which rustup
> /home/william/.cargo/bin/rustup

rustup toolchain install 1.47
rustup default 1.47

which rustc
> /home/william/.cargo/bin/rustc

cargo new demo
cd demo
cargo run
> Hello, world!


NOTE: I don't have access to any armv7 hardware so I can't exactly test this easily :(

Tested it on an armv7 system and all of this works fine on armv7.

Any update of your test with bundled llvm on 1.49?

No - attempting the build causes an out-of-memory on the build servers for all arches during the build process. I have been unable to successfully build with bundled llvm at this time. I need to revisit this to see why. Certainly the fact that you can use the upstream rust that has bundled llvm vs our rust that uses the platform llvm does hint that there is an incompatibility between our llvm and rust's expectations. 

My ideal outcome in this matter would be that we just use the bundled llvm since it has stronger quality assurances from upstream rust than using our own llvm - using our own can lead to exactly this kind of issue.

thats because we build bundled llvm with debuginfo enabled, which causes this issue. I had to workaround that for bootstrapping Step. let me see if I can upstream this patch to tumbleweed..

Update to version 1.50 fixes the build on armv7. Verified locally.
