I did some more digging. I saw that the test in the CI fails with permission

I thought that maybe the problem is that, the program to be debugged by `dbg`
does not compile with the compiler that includes my changes. I decided to just
compile the test file with my modified compiler. I copied the test file.
Removed one include that is only needed for manual debugging and recreated the
command used in the CI as much as I could. The command looks like this now:
```
/home/spaits/repo/llvm-project/build/bin/clang++ -pthread
--target=x86_64-unknown-linux-gnu /home/spaits/cpp/deb.cpp -o

Because of the GCC 13+ prereq. I did not build libc++ for my self, but used the
one available on my machine.
This way the file has compiled successfully.
I will still try to run the tests myself.
Until that if you have any idea what should I, do what wen possibly wrong pleas
share that with me.
Thanks.
