[Eugen P. <eu...@qn...>]

Runtime-Error in LitWindow for method:
void rule_base::execute_immediate(const constraint_solver *a_solver) =
const {

auto_ptr<value_assign_base> v(evaluate(a_solver));

v->do_assign(a_solver->get_symbol_table());

}

Method rule_base::execute_immediate(const constraint_solver *a_solver) =
can lead to memory access violation.
Reason: local variable auto_ptr<value_assign_base> v can evaluate to =
NULL if the target is itself an accesor.

Correction:

void rule_base::execute_immediate(const constraint_solver *a_solver) =
const

{

auto_ptr<value_assign_base> v(evaluate(a_solver));

if( NULL !=3D v.get() ) v->do_assign(a_solver->get_symbol_table());

}
