    Description

      The following program is a test for GROOVY-5883:

                  @groovy.transform.CompileStatic
                  class Test<T> {
                      def map(Closure<T> mapper) { 1 }
                      def m1(Closure<Boolean> predicate) {
                          map { T it -> return predicate(it) ? it : null }
                      }
                      def m2(Closure<Boolean> predicate) {
                          map { T it -> return predicate(it) ? it : (T) null }
                      }
                      def m3(Closure<Boolean> predicate) {
                          Closure<T> c = { T it -> return predicate(it) ? it : null }
                          map(c)
                      }
                  }
                  def t = new Test<String>()
                  assert t.m1{true} == 1
                  assert t.m2{true} == 1
                  assert t.m3{true} == 1
      

      This fails to execute in static compilation mode only with a VerifyError in the generated Closure#doCall methods in any of m1/m2/m3.created
