re PR fortran/35698 (lbound and ubound wrong for allocated run-time zero size array)
2008-03-29 Paul Thomas <pault@gcc.gnu.org> PR fortran/35698 * trans-array.c (gfc_array_init_size): Set 'size' zero if negative in one dimension. PR fortran/35702 * trans-expr.c (gfc_trans_string_copy): Only assign a char directly if the lhs and rhs types are the same. 2008-03-29 Paul Thomas <pault@gcc.gnu.org> PR fortran/35698 * gfortran.dg/allocate_zerosize_3.f: New test. PR fortran/35702 * gfortran.dg/character_assign_1.f90: New test. From-SVN: r133710
