            Bug ID: 51271
           Summary: Sanitizer -shared-libsan is unusable on Ubuntu
                    20.04/18.04 and clang-12/10
           Product: clang
           Version: 12.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

If I compile a simple program (sample.cpp):

#include <cstdio>

int main() {
  printf("Hello, World");
  return 0;
}

with a shared sanitizer library, i.e.

clang++-12 -fsanitize=address -shared-libsan sample.cpp -o sample

I am getting the following error when running ./sample:

./sample: error while loading shared libraries: libclang_rt.asan-x86_64.so:
cannot open shared object file: No such file or directory

I am getting this error for the sample code on my local machine (Ubuntu 20.04
and clang-12), as well as for the production code on our build runner (Ubuntu
18.04 and clang-10).
