# This is a regression test. There was a bug where if an upvalue for an
# earlier local (here "a") was captured *after* a later one ("b"), then it
# would crash because it walked to the end of the upvalue list (correct), but
# then didn't handle not finding the variable.

fun f() {
  var a = "a";
  var b = "b";
  fun g() {
    print(b); # expect: b
    print(a); # expect: a
  }
  g();
}
f();
