Package: clang-6.0 Version: 1:6.0.1-2 Severity: important Dear Maintainer,
First, I'm not really sure clang is at fault here since this issue requires a specific combination involving the clang++ compiler, the gold linker and the sanitizers options. Basically, with a specific combination of these tools the link step produces a warning, which may result in a link error if '-Wl,--fatal-warnings' is used. $ cat main.cpp int main(){ return 0; } $ /usr/bin/clang++-6.0 -o main.o -c main.cpp -fsanitize=address $ /usr/bin/clang++-6.0 -o main main.o -fsanitize=address -fuse-ld=gold /usr/bin/ld.gold: warning: discarding version information for __libc_stack_end@GLIBC_2.2.5, defined in unused shared library /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 (linked with --as-needed) * Using clang-6.0 (as a C compiler) or clang++-7 (1:7~svn331965-1) does not solve the issue * Using g++-8 instead of clang++-6.0 works fine * Using '-fuse-ld=bfd', '-fuse-ld=lld' or no flags (bfd default) works fine * Using another ('undefined', 'thread' or 'memory') sanitizer is also broken while no sanitizers works fine Sylvain -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (990, 'testing'), (800, 'stable-updates'), (800, 'stable'), (700, 'unstable'), (90, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.16.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8), LANGUAGE= (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages clang-6.0 depends on: ii binutils 2.31.1-1 ii libc6 2.27-5 ii libc6-dev 2.27-5 ii libclang-common-6.0-dev 1:6.0.1-2 ii libclang1-6.0 1:6.0.1-2 ii libgcc-7-dev 7.3.0-25 ii libgcc1 1:8.1.0-10 ii libjsoncpp1 1.7.4-3 ii libllvm6.0 1:6.0.1-2 ii libobjc-7-dev 7.3.0-25 ii libstdc++-7-dev 7.3.0-25 ii libstdc++6 8.1.0-10 Versions of packages clang-6.0 recommends: ii libomp-dev 6.0.1-1 ii llvm-6.0-dev 1:6.0.1-2 ii python 2.7.15-3 Versions of packages clang-6.0 suggests: pn clang-6.0-doc <none> pn gnustep <none> pn gnustep-devel <none> -- no debconf information
