current gcc 12.4.0 bug

[<tlaronde%kergis.com@localhost>]

I'm running current and stumbled on that:

exec.c: In function 'shellexec':
exec.c:145:46: error: '%s' directive argument is null
[-Werror=format-overflow=]
  145 |         (void)fprintf(stderr, "do_qfilename (%s): %d\n",
      |                                              ^~
cc1: all warnings being treated as errors

While the argument is not NULL.

It's a bug in gcc see:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90036

With this around, how can we be sure that the generated code is
correct?
