SIGSEGV with libpq and rust:alpine3.13, but not alpine:3.13 #85
Description
I found a segfault when using postgres on the rust docker images that I can't reproduce with rustc from the official alpine images:
Binary built on alpine:* images (3.13 and edge):
foo_1 | [*] Trying to cause segfault
foo_1 | [+] No segfault! Result is: ERR (but that's ok)
Binary built on rust:alpine3.13 image:
foo_1 | [*] Trying to cause segfault
alpine-pq-repro_foo_1 exited with code 139
The debian based rust container and compiling/running it on Arch Linux works fine.
I have a minimal reproducer, to reproduce it run docker-compose up --build, the required files are:
Dockerfile
#FROM alpine:edge # works
#FROM alpine:3.13 # works
FROM rust:alpine3.13
RUN apk add cargo postgresql-dev
WORKDIR /app
COPY . .
RUN cargo build --release
ENTRYPOINT ["/app/target/release/alpine-pq-sigsegv-repro"]src/main.rs
use diesel::PgConnection;
use diesel::Connection;
fn main() {
println!("[*] Trying to cause segfault");
let r = PgConnection::establish("postgres://postgres:postgres@127.0.0.1/asdf");
println!("[+] No segfault! Result is: {}", if r.is_ok() { "OK" } else { "ERR (but that's ok)" });
