sparc64-unknown-linux-gnu fails

[gnzlbg]

With error (see here):

thread '<unnamed>' panicked at 'assertion failed: signal(libc::SIGPIPE, libc::SIG_IGN) != libc::SIG_ERR', libstd/sys/unix/mod.rs:85:9
note: Run with `RUST_BACKTRACE=1` for a backtrace.
error: process didn't exit successfully: `qemu-sparc64 /target/sparc64-unknown-linux-gnu/release/deps/slice_deque-5da7fc08593c2b4e` (signal: 4, SIGILL: illegal instruction)

It doesn't look like cross tests are periodically run against travis (e.g. every 24-h), is that so? If so running the test suite periodically might help discover breakage introduced upstream.

The same error for i686-android #140

[gnzlbg]

I've reported this upstream: rust-lang/rust#55204

This appears to happen when the libstd runtime is initialized.

This doesn't reproduce anymore as of cross 2f24bd4.

Sample code demonstrating it works is as of Rust 1.61.0 stable.

tmp_dir=$(mktemp -d)
cd "$tmp_dir"
git clone https://github.com/cross-rs/cross
cd cross
# checkout specific version known to work: latest commit on main tested.
git checkout 2f24bd4a81fcb375bc0acf9d0aa6a80d8f4123a0
cargo build

cd ..
git clone https://github.com/gnzlbg/slice_deque
cd slice_deque
"$tmp_dir"/cross/target/debug/cross test --target sparc64-unknown-linux-gnu

cd ~
rm -r "$tmp_dir"

All the tests pass, suggesting the issue has been fixed upstream.
