Crashes with coroutines and curl 8.10.1

Since 1.10.2024, our application started to crash:

app-1      | [2024-10-04 06:52:16 $119.0]       WARNING Server::check_worker_exit_status(): worker(pid=711, id=0) abnormal exit, status=0, signal=11
app-1      | A bug occurred in OpenSwoole-v22.1.2, please report it.

app-1      | OS: Linux 6.6.51-gentoo #1 SMP PREEMPT_DYNAMIC Fri Sep 13 23:06:02 UTC 2024 x86_64
app-1      | GCC_VERSION: 13.2.1 20240309
app-1      | OPENSSL_VERSION: OpenSSL 3.3.2 3 Sep 2024
app-1      | PHP_VERSION : 8.3.11

From our Dockerfile:

FROM php:8.3.11-alpine3.20

RUN apk upgrade --no-cache \
    && apk add --no-cache \
    curl-dev

# Install extensions
RUN pecl install -D 'enable-openssl="yes" enable-hook-curl="yes"' openswoole-22.1.2

There is a lot of inter-service communication between the microservices via Guzzlehttp and it only happens with coroutines enabled.

That time, curl was upgraded in Alpine 3.20: https://gitlab.alpinelinux.org/alpine/aports/-/commit/e17ad295e0810e938f9c4d61c21e44eaf1a59b51 https://gitlab.alpinelinux.org/alpine/aports/-/commit/badfda8e31a0b6e87e78237d7ee4455b35cd4c10

After reverting back to Alpine 3.19 it works fine.

Alpine 3.19: curl 8.9.1 Alpine 3.20: curl 8.10.1
