  *Note on debugging*: The version of `gdb` installed by default is [ancient and considered harmful](https://wiki.freebsd.org/GdbRetirement).
  It is not suitable for debugging a multi-threaded C++ program, not even for getting backtraces. Please install the package `gdb` and
  use the versioned gdb command (e.g. `gdb7111`).
