Description

The following code runs without problem in Groovy 2.5.14:

import groovy.transform.CompileDynamic
import groovy.transform.CompileStatic

@CompileStatic
class DynamicArrayAccess {
    @CompileDynamic
    DynamicArrayAccess() {
        Node node = loadXml()
        println node.b[0].text()
    }

    private static Node loadXml() {
        new StringReader("<a><b>hello</b></a>").withCloseable { new XmlParser().parse(it) }
    }

    static void main(String[] args) {
        new DynamicArrayAccess()
    }
}

However, if you try to run it in Groovy 3.0.9, you'll get an exception during compilation. Extracting problematic code to a separate method fixes the problem.

BUG! exception in phase 'class generation' in source unit '/home/nik/IdeaProjects/untitled19/src/main/groovy/DynamicArrayAccess.groovy' At line 9 column 21
On receiver: node.b with message: getAt and arguments: 0
This method should not have been called. Please try to create a simple example reproducing
