Hi all, I found that, when `clang -Wl,-v` and head command are used with pipeline, and clang uses absolute path, a.out will be intermittently generated. I am not sure whether this is a bug of clang or a bug of head command. Below command demonstrate that:
```
$ rm -rf a.out ; date ; ~/software/clang+llvm-17.0.2-x86_64-linux-gnu-ubuntu-22.04/bin/clang -Wl,-v 2>&1 | head -n 1 ; stat a.out ; ls -lh a.out ; file a.out
