Fortran: error recovery on rank mismatch of array and its initializer
gcc/fortran/ChangeLog:
PR fortran/102715
* decl.c (add_init_expr_to_sym): Reject rank mismatch between
array and its initializer.
gcc/testsuite/ChangeLog:
PR fortran/102715
* gfortran.dg/pr68019.f90: Adjust error message.
* gfortran.dg/pr102715.f90: New test.
