Description

The following test case illustrates the issue, which only occurs if there are more than one argument to the call:

package org.codehaus.groovy.classgen.asm.sc.bugs

import groovy.transform.stc.StaticTypeCheckingTestCase
import org.codehaus.groovy.classgen.asm.sc.StaticCompilationTestSupport

@Mixin(StaticCompilationTestSupport)
class GroovyVerifyErrorBug extends StaticTypeCheckingTestCase {

    @Override
    protected void setUp() {
        super.setUp()
        extraSetup()
    }

    void testShouldNotThrowVerifyErrorIfUsingImplicitCall() {
        assertScript '''
class Foo {
    Closure isUpper = { String it, String up -> it.toUpperCase() == up }

    def test(String str) {
        isUpper(str, 'ABC') // replace with isUpper.call(str,'ABC') and no error
    }
}
def foo = new Foo()
assert foo.test('abc')
'''
    }
}

Using .call doesn't throw any VerifyError.
