+// Bug 1316181
+
+// There are locals with different values here to ensure that the
+// local.get at the end picks up the right one even if the stack might
+// have become unbalanced by a failure to adjust SP along the branch
+// edge.  The logic is that we use SP-relative addressing, and if the
+// actual SP is not what the compiler thinks it is we will read
+// something other than the expected value.
