[GROOVY-9937] internal compiler error during instruction selection

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 3.0.7
• Component/s: Static compilation
• Assignee: Unassigned

Description

I have the following (incorrect) program

 

class Foo {
  static void foo() {
    return 1   
  }
}

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.
