Yes, definitely.
Kirill, as seem to use code which does trigger the bug, you may want to
switch using 'R-patched', i.e., 

  > R.version.string
  [1] "R version 3.3.0 Patched (2016-05-09 r70591)"

   ( where the subversion revision must be >= 70591 )

I'm pretty sure that your hope will be fulfilled.
