[ESS] Another indentation error

[Star Ying]

So I have another indentation error with ess and emacs that I have run into. For the example below:

data example;
     merge
          lib.data lib.data2

          %if val=ue %then %do;
               lib.data3
          %end;
          ;
by var;

The last line produces an error if I hit tab or if I try to indent that region. Emacs produces the error "invalid search bound (wrong side of point)". The code itself is valid and runs in sas proper. Is this just me or is this a reproducible error?
