    fix misallocation of some <fix> procedures
    
    * module/language/tree-il/analyze.scm (analyze-lexicals): When stepping
      into a non-tail form, we know that labels allocation will be invalid,
      so use an empty labels set.  Fixes http://debbugs.gnu.org/9769.
    
    * test-suite/tests/tree-il.test ("labels allocation"): Add a test.
