--- Comment #3 from Dominique d'Humieres  ---
The check has been introduced at revision r141931 and is now

  /* We are told not to check dependencies.
 We do it, however, and issue a warning in case we find
one.
 If a dependency is found in the case
 elemental == ELEM_CHECK_VARIABLE, we will generate
 a temporary, so we don't need to bother the user.  */
  gfc_warning (0, "INTENT(%s) actual argument at %L might "
   "interfere with actual argument at %L.",
   intent == INTENT_OUT ? "OUT" : "INOUT",
   >where, >where);

The warning is unconditional, but it should be easy to replace the 9 with some
suitable option.

--- Comment #2 from Ian Harvey  ---
The spurious warning is issued regardless of whether warnings are requested or
not (i.e. it is reported with a command line of just `gfortran -c file.f90`). 
The warning is issued even if -Wno-aliasing is explicitly provided.

Started with GCC5 (no warning with 4.8 or 4.9) up to trunk (9.0).

If you ask for warnings, don't complain about false positive nor missed ones!-(
