Thanks for the reminder, I confirmed that this is the problem caused by the openssl static link, it behaves almost the same as https://users.rust-lang.org/t/sigsegv-with-program-linked-against-openssl-in-an-alpine-container/52172, and the problem it describes exists so far.

As for why I was able to build normally a week ago, it is composed of multiple coincidences😂. As a module of a C program written in Rust, it is configured as a static C ABI library:

[lib] crate-type = ["staticlib"]

On the final build I used the following docker script:

FROM ${ALPINE} AS cleardns RUN apk add build-base cmake git openssl-libs-static COPY ./ /cleardns/ COPY --from=rust-mods /tmp/libassets.a /cleardns/src/target/release/ COPY --from=rust-mods /tmp/libto_json.a /cleardns/src/target/release/ WORKDIR /cleardns/bin/ RUN cmake -DCMAKE_EXE_LINKER_FLAGS=-static .. && make && strip cleardns && mv cleardns /tmp/

When finally compiling into an executable file, the library written by Rust is statically linked. Since CMAKE_EXE_LINKER_FLAGS is specified as -static, all libraries including openssl will be completely statically linked, which inadvertently avoids this problem.

Since openssl is cumbersome to build on musl-based systems, I would consider using rustls instead of openssl on Alpine.
