I don't know who's the current maintainer of the Arch Linux D packages. ldc1.7.0 from the Arch repositories doesn't work with -fsanitize=address right now, it fails to link. I originally filed an ldc bug here:

https://github.com/ldc-developers/ldc/issues/2488

But it turns out that the pre-built version from dlang.org works fine, so I opened an Arch bug here:

https://bugs.archlinux.org/task/57026

I will look into this.

Grasping the occasion to thank you for your work maintaining it.

Thanks. The official package ships with a renamed copy of the LLVM compiler-rt library (matching the LLVM version LDC was built with), libldc_rt.asan-x86_64.a. If a copy is out of the question, a dependency on the package containing that lib (original name: libclang_rt.asan-x86_64.a) and a symlink may do the job.
libFuzzer is handled like this as well. See https://github.com/ldc-developers/ldc/blob/v1.7.0/CMakeLists.txt#L742-L795.

Thanks! Now I don't need track down what was missing.

Small question, is only *.a needed and not *.so?

Extra info:
LDC should also recognize the libclang_rt.asan and libclang_rt.fuzzer libraries if they are in the same path where LDC would try to find the libldc copies. So the symlink is not even necessary in that case.

On Arch these files are stored in "/usr/lib/clang/5.0.1/lib/linux/",
and the archlinux package tool doesn't like symlinks that point
outside of the package. So a patch would be my only choice.

So my solution is:
sed -i "s/libclang_rt/clang\/$_llvmversion\/lib\/linux\/&/g" driver/linker-gcc.cpp

Would be nice if a future version of ldc checked this directory, or
if it would be possible to send in a constant to gnumake with this path.

The ldc-1:1.7.0-2 is now pushed and -fsanitize=address works,
the -fsanitize=fuzzer option should work when this issue has been
fixed: https://bugs.archlinux.org/task/56023

Yeah, I have this PR that I didn't look at for a while:
