Jiří Vaněk has updated the pull request incrementally with one additional commit since the last revision:

  Temporary workaround around tests being order-sensitive
  
  As -g is now making some disassmebld code not asemble-able back, and
  order of tests is not deterministic, and Options are static, thus if -g
  is now set in some test, it is not unset in other tests.
  
  Real fix is to move Options out of static context to context of
  environment as it is done for jcoder.
