      When attempting to run the script provided by the "Create Memory Trace Points" menu option, there are three main problems on Arch Linux:
      1. The call to find for libc.so.6 fails since /lib is a symlink. To work around this, you can use /lib/ for the path instead.
      2. The non-inlined _ret functions are decorated automatically by the call to perf probe, likely due to the %return in the function name, causing match_tracepoints to incorrectly delete valid entries.
      3. Some entries queried with perf probe -l have multiple lines, which break finding the "bad" probes that are deleted in match_tracepoints.
