Fortran: Avoid var initialization in interfaces [PR54753]
Intent(out) implies deallocation/default initialization; however, it is
pointless to do this for dummy-arguments symbols of procedures which are
inside an INTERFACE block. – This also fixes a bogus error for the attached
included testcase, but fixing the non-interface version still has to be done.
PR fortran/54753
gcc/fortran/ChangeLog:
* resolve.c (can_generate_init, resolve_fl_variable_derived,
resolve_symbol): Only do initialization with intent(out) if not
inside of an interface block.
