Bug: cargo test crashes on i386

[tenzap]

Describe the bug

While running the test suite of the Debian package on x86 (i386) architecture, we found that the tests are crashing (signal: 11, SIGSEGV: invalid memory reference)

Could you have a look?

This also crashed with 6.4.0

There is no crash on the other archs and tests pass.

Steps to reproduce

Command:
['env', 'RUST_BACKTRACE=1', '/usr/bin/cargo', '-Zavoid-dev-deps', 'test', '--verbose', '--verbose', '-j4', '--target', 'i686-unknown-linux-gnu', '--all-targets', '--all-features']

Full log for 6.5.3 available at https://debusine.debian.net/debian/developers/artifact/2529250/file/rust-simsimd:@-stdout
Full log for 6.4.0 at https://ci.debian.net/data/autopkgtest/testing/i386/r/rust-simsimd/64843062/artifacts.tar.gz

Hi @tenzap! It's a pretty long dump and I'm not sure about where to look. Is there a specific test you can point me to?

[tenzap]

Thanks for considering this.

Unfortunately not. The dump looks long because in Debian the build system prints all commands to build all rust dependencies. But you are mostly interested in the last one which is the one of simsimd.

When running the test it crashes almost immediately on when starting to run the tests of simsimd. Just try yourself with i686. I'm not even sure the 1st test can actually finish.

I can't really help more sorry.
