Hello dear Hackers I'm trying to upgrade to v17 and encountering a strange issue.
I've made a minimal reproduction that works with 16.4 but fails with 17.0, it also works without the "-static" compile flag: # syntax=docker/dockerfile:1 > FROM alpine:3.20 AS builder > > # Fails with 17.0 succeeds with 16.4 > ARG PG=17.0 > > USER root > RUN apk update && apk add --no-cache --update-cache \ > ca-certificates-bundle \ > util-linux-dev \ > clang17-dev \ > execline-dev \ > llvm18-dev \ > libedit-dev \ > libxml2-dev \ > build-base \ > net-tools \ > clang17 \ > zlib-dev \ > autoconf \ > automake \ > busybox \ > llvm18 \ > icu-dev \ > cmake \ > bison \ > flex \ > perl \ > curl \ > bash \ > flex > WORKDIR /app > > RUN curl -L > https://github.com/openssl/openssl/releases/download/openssl-3.3.2/openssl-3.3.2.tar.gz > > openssl.tar.gz > RUN mkdir openssl && tar --extract --file=openssl.tar.gz --strip-components=1 > --directory=openssl && rm openssl.tar.gz > RUN cd openssl && CC=clang CXX=clang++ perl ./Configure \ > linux-$(uname -m) \ > --prefix=/usr \ > --libdir=lib \ > --openssldir=/etc/ssl \ > enable-ktls \ > shared \ > no-zlib \ > no-async \ > no-comp \ > no-idea \ > no-mdc2 \ > no-rc5 \ > no-ec2m \ > no-sm2 \ > no-sm4 \ > no-ssl3 \ > no-seed \ > no-weak-ssl-ciphers \ > -Wa,--noexecstack && \ > perl configdata.pm --dump && \ > make -j$(nproc) && make install > > RUN curl -L https://ftp.postgresql.org/pub/source/v$PG/postgresql-$PG.tar.bz2 > > postgresql.tar.bz2 > RUN mkdir postgresql && tar --extract --bzip2 --file=postgresql.tar.bz2 > --strip-components=1 --directory=postgresql && rm postgresql.tar.bz2 > RUN cd postgresql && CC=clang CXX=clang++ ./configure --with-openssl > --with-libedit-preferred --with-uuid=e2fs --with-libxml --prefix=/usr/local > RUN cd postgresql/src/include && CC=clang CXX=clang++ make && make install > RUN cd postgresql/src/common && CC=clang CXX=clang++ make && make install > RUN cd postgresql/src/port && CC=clang CXX=clang++ make && make install > RUN cd postgresql/src/interfaces/libpq && CC=clang CXX=clang++ make && make > install > > COPY <<EOF ./main.cpp > #include <algorithm> > #include <iostream> > #include <chrono> > #include <thread> > #include <cstring> > #include <csignal> > #include <vector> > > #include <libpq-fe.h> > > void sig_handler(int /*_signo*/, siginfo_t * info, void * /*_ctx*/) { > raise(info->si_signo); > _exit(EXIT_FAILURE); > } > > void registerSignalHandlers() { > std::vector<int> signals = { > // Signals for which the default action is "Core". > SIGABRT, // Abort signal from abort(3) > SIGBUS, // Bus error (bad memory access) > SIGFPE, // Floating point exception > SIGILL, // Illegal Instruction > SIGIOT, // IOT trap.
