如何解决 Alpine WSL 中多线程 Rust 应用程序中的分段错误？

Question

If I run cargo install-update --list I get a Segmentation fault .

I've noticed the same if I run my CLI applications which use tokio runtime and have.network requests with reqwest . If I run cargo install <package> that works fine. Meaning CLI applications can access the.network.

This is happening in Alpine Linux install in WSL 2 on Windows.

dmesg shows

[54391.796247] cargo-install-u[11344]: segfault at 0 ip 0000000000000000 sp 00007ffdf8e9c398 error 14

Any hints would be appreciated. I am not sure how to troubleshoot and where to address the problem - whether it is WSL, Alpine Linux, Rust, Tokio, reqwest or somewhere else.

Cargo version: cargo 1.66.0 (d65d197ad 2022-11-15)

Cargo-Update version: cargo-update v11.0.0

The related question (thanks, SO.) provides a useful hint about the OpenSSL dependency on Linux systems.

Indeed, following the answer there and using rusttls

reqwest = { version = "0.11.13", default-features = false, features = ["json", "rustls-tls"] }

instead of the default native-tls, fixes the issue.

The reqwest docs list OpenSSL (1.1) as a requirement on Linux. Alpine contains v3 packages with 1.1 compatibility packages but I'm not sure which ones should be installed or if they are by default.

So, hopefully there would be an option to install whatever necessary package and not to have to change the app dependencies.

In this case I could fix my app that had the Segfault but that won't work for others, like cargo-update for example.
