Crash with clang sanitizers (on Debian) #81470

Open stevenwdv opened 9 months ago

stevenwdv commented 9 months ago

I must be doing something wrong because I cannot get address sanitizer or memory sanitizer to work without randomly crashing on a minimal C program, even on a fresh install via Docker. I can't imagine this not being reported but yet I can't find anything on this.

Repro

#!/usr/bin/env sh
set -eu

docker run --interactive debian sh <<'EOF'

set -eu
export DEBIAN_FRONTEND=noninteractive
apt-get update && apt-get install -y clang

The docker part if of course optional, but I used it to verify that it was not just my install.

I did try explicitly adding -fPIE -Wl,-pie but it did not make a difference.

I had the same thoughts as the reporter, only difference is that we use ubuntu images (mantic), it can be reproduced there, too. Usually, it fails about 8-10 times from 50ish runs. However, using ubuntu:noble (not yet released LTS version, packed with clang-17), it successfully run for more than 2K times. Using clang-16 in ubuntu:noble produces the crash, so somewhere between 16 and 17 it got fixed. Exact versions: Ubuntu clang version 16.0.6 (19build1) Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin

and

Ubuntu clang version 17.0.6 (5build1) Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin

rustyrussell commented 8 months ago

Same here, Ubuntu mantic, but also under our CI. It's intermittant, but compiled code crashes 219 of 1000 runs.

Here's our trivial code:

/* Test program generated by configurator. */
int main(int argc, char *argv[]) {
    (void)argc;
    (void)argv;
return __builtin_choose_expr(1, 0, "garbage");}

It's compiled with clang -Wall -Wundef -Wmissing-prototypes -Wmissing-declarations -Wstrict-prototypes -Wold-style-definition -Werror -std=gnu11 -g -fstack-protector-strong -fsanitize=address -fno-sanitize-recover=address -fsanitize=undefined -fno-sanitize-recover=undefined -I/usr/local/lib -L/usr/local/lib -I/usr/include/postgresql -oconfigurator.out configuratortest.c.

Without -fsanitize=address there are no failures at all.

Using LSAN_OPTIONS=verbosity=1:log_threads=1 here are a successful and an unsuccessful run:
