Is the generated code correct?
The created methodNode says it's:
logicArg assoc
| n structure x list len range |
x := LogicRef new.
x := LogicRef new.
n := LogicRef new.
x := LogicRef new.
structure := LogicRef new.
n := LogicRef new.
x := LogicRef new.
range := LogicRef new.
n := LogicRef new.
range := LogicRef new.
len := LogicRef new.
...
The problem is that the method's selector is #logicArg which has 0
arguments, but somehow it has an argument: assoc. And some assignments
seem to be unnecessary.
