a = b
The problem is that the LHS is REAL(4) while the RHS is REAL(8). Thus, the
expression is not <variable A> = <variable B> but
<variable A> = __convert_i8_i4 (<variable B>)
But trans-array's gfc_trans_assignment_1 contains:
if (gfc_is_reallocatable_lhs (expr1)
&& !(expr2->expr_type == EXPR_FUNCTION
&& expr2->value.function.isym != NULL))
lss->is_alloc_lhs = 1;
As expr2->value.function.isym is set (expr2->value.function.isym->id ==
GFC_ISYM_CONVERSION), the is_alloc_lhs is not set. Hence, the bound checking
code is inserted.
