Eric Milles updated GROOVY-9937:
--------------------------------
Priority: Minor (was: Major)
> internal compiler error during instruction selection
> ----------------------------------------------------
>
> Key: GROOVY-9937
> URL: https://issues.apache.org/jira/browse/GROOVY-9937
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 3.0.7
> Reporter: Thodoris Sotiropoulos
> Priority: Minor
>
> 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.
>
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
