Compiler bug when spread operator is used twice

[jpragey]

The following code:

class A(){}
class B(){shared String qname() => "";}

void f(B[] bs) {
    value v = bs *.qname()*.size;
}

breaks the compiler:

error: compiler bug: null at com.redhat.ceylon.compiler.java.codegen.ExpressionTransformer.transformSpreadOperator(ExpressionTransformer.java:3507)
error: compiler bug: visitor didn't yield any result at com.redhat.ceylon.compiler.java.codegen.ExpressionTransformer.transformExpression(ExpressionTransformer.java:313)
error: compiler bug: visitor didn't yield any result at unknown
Note: Created module bug/1.0.0
ceylon compile: Fatal error: The compiler exited abnormally (4) due to a bug in
the compiler.
Please report it:
