awc causing SIGSEGV on Alpine

[untbu]

Expected Behavior

The creation of the new awc client should work as it does on Ubuntu or there should be an error.

Current Behavior

The first time an awc client is created, the program stops without any error. After the program is restarted and again creates an Awc client, it stops with error code 139 (SIGSEGV). I suspect that the first error is also a SEIGSEGV but it's catched by someone. Docker output (the second Finished dev is after the container is restarted by docker):

Steps to Reproduce

1. Download example code: awc-alpine-sigsegv.zip
2. Run docker-compose up

Context

I am trying to write a program that receives logs via post requests and stores them in a database. Specific events should be reported using discord webhooks.

Your Environment

The code is compiled and executed inside an Alpine docker container.

• Rust version: rustc 1.68.2 (9eb3afe9e 2023-03-27)
• Gcc version: 12.2.1 20220924 (Alpine 12.2.1_git20220924-r4)
• Actix Web version: 4.3.1
• Awc version: 3.1.1
• Alpine docker image version: 3.17

Edit

It looks like this is an issue with the openssl feature. When using the rustls feature instead everything is working as expected. Maybe this is an openssl issue and not an awc one?
