BTW, looking at the 
  #pragma GCC diagnostic ignored "-Wanalyzer-null-argument"
at
https://github.com/libguestfs/libguestfs/blob/f19fd566f6387ce7e4d82409528c9dde374d25e0/df/main.c#L317
I'm guessing that this was due to PR analyzer/99196, due to the:

    name = strdup (drvs->uri.orig_uri);
    if (name == NULL)
      error (EXIT_FAILURE, errno, "strdup");
    p = strrchr (name, '/');

where the analyzer didn't "know" that the error call would terminate the
program; so hopefully this is also fixed now.
