>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 3.0.7
>            Reporter: Thodoris Sotiropoulos
>            Assignee: Eric Milles

> I have the following (incorrect) program
>  
> {code:java}
> class Foo {
>   static void foo() {
>     return 1   
>   }
> }
> {code}
> The compiler crashes during the instruction selection phase producing the following output. From what I understand is that the type checker misses the error, and the compiler crashes during bytecode generation.
