[PPL-devel] drop_some_non_ineger_points raises " Invalid memory access of location 0x0 rip=0x1011a50ca "

Hello,

I may probably wrongly use the PPL's Java interface, but here are my naive questions among others,

1. Is it normal that the following codes raise this error " Invalid memory access of location 0x0 rip=0x1011a50ca " ? (The JAVA's interface for 'drop_some_non_integer_points" requies an integer or variable-set plus an integers as its parameters, rather than C's " void drop_some_non_integer_points (Complexity_Class complexity=ANY_COMPLEXITY)" ) . .....cod Constraint c = new Constraint(le_5Z, Relation_Symbol.GREATER_THAN, le_X); Constraint_System cs = new Constraint_System(); cs .add(c); NNC_Polyhedron ph2=new NNC_Polyhedron(cs); ph2.drop_some_non_integer_points(new Integer(1)); ......

2. I don't find ways to specify a constraint with explicite rational or real numbers, like x>=2.5, because the 'Coefficient' only accepts integers. Does than mean that I am obliged to use 2 *x >=5 rather than x >2.5?

Thanks. zell.
