typo in record passes compile

I wrote this program, making a typo:

typedef tree<a>  = Leaf a | Node {left is tree , right is tree };

t1 is tree<number> = Node { left=Leaf 1,right=Node { left=Leaf 10, right=Leaf 2 }};

t2 is tree<number> = Node { left=Leaf 1,right=Node{ left=Leaf 2,rigt=Leaf 3 }};

println t1;
println t2;

walk t is tree<'a> -> list<'a> = (
    case t of 
    Leaf v : [v];
    Node {left,right} :  (walk left) ++ (walk right);
    esac;
    );

println(walk t1);
println(walk t2);

in t2 the last node is rigt not right. Compile passes and program fails with:

Node {left=Leaf 1, right=Node {left=Leaf 10, right=Leaf 2}}
Node {left=Leaf 1, right=Node {left=Leaf 2, rigt=Leaf 3}}
[1,10,2]

Am I doing something wrong or is it a bug ?
