gcc Apple Silicon missing AddressSanitizer/UBSanitizer libraries?

[dgazzoni]

I have a problem trying to use AddressSanitizer and/or UBSanitizer with Homebrew's gcc on Apple Silicon. It does not happen on Intel.

1. Install gcc 11 or 12: brew install gcc or brew install gcc@12
2. Create the following simple C program as test.c:

int main() {
    return 0;
}

3. Compile with AddressSanitizer and/or UBSanitizer:

gcc -fsanitize=address -o test test.c # also fails with gcc-12, or -fsanitize=undefined

4. Rather than a successful compile, the following errors are output:

ld: library not found for -lasan # or -lubsan if using -fsanitize=undefined
collect2: error: ld returned 1 exit status

Indeed, looking at the files on /opt/homebrew/Cellar/gcc/11.3.0/lib/gcc/11 on my Apple Silicon Mac, there's no libasan.dylib or libubsan.dylib. On the Intel Mac, they are present in /usr/local/Cellar/gcc/11.3.0/lib/gcc/11.

I tried to look at the formulas for gcc, to see whether there was some kind of special-casing for either Apple Silicon or Intel, but I was unable to find any.

Can anyone else reproduce? Should I file a bug?

GCC on ARM is a pre-release version, it isn't officially supported yet.

But if you're lucky @fxcoudert might be able to help you with this.

I think the sanitizer runtime libraries are simply not supported on aarch64-apple-darwin at this point.

hello @dgazzoni I'm running into the same problem, did you find a way how to use AddressSanitizer with gcc m1?

@fxcoudert I am able to use clang++ -std=c++17 -o x x.cpp -fsanitize=address -g But, using g++ fails. Is this an unsolvable issue? Like will the support for this ever come in future?

[fxcoudert]

“Impossible to see, the future is.”

@vedanta28 Not sure the compilation option does anything at all actually

I'm affected by this as well, using GCC 13.1.0 aarch64-apple-darwin22.

@fxcoudert do you have any information on how I might follow the development progress on GCC's support for aarch64-apple-darwin?

See https://github.com/iains/gcc-13-branch and related repos from the same user.

[vedanta28]

@fxcoudert Actually, there is another issue too, which came to me after installing gcc 13.1.0. Some code which earlier used to compile is not compiling anymore. I am not sure if I should downgrade it or remain for the bugs to be fixed.

[fxcoudert]

I have verified the issue and filed it here: iains/gcc-darwin-arm64#107

[dpo]

I have the same issues with both the gcc-12 and gcc-13 toolchains, for both arm64 and intel architectures. I haven't tried older toolchains.

The platforms where libsanitizer is supported is limited: https://github.com/iains/gcc-darwin-arm64/blob/master-wip-apple-si/libsanitizer/configure.tgt

It doesn't support arm64 at all on macOS, and now in addition does not support macOS Ventura or later on x86_64 (see iains/gcc-darwin-arm64@e722a1f).
