6172	Issue with for loop index variables in conditional expression within algorithm	Francesco Casella	Mahder Alemseged Gebremedhin	"Consider the following test model

{{{#!mo
class matrixAdd
  parameter Real[3,2] m={{1,2},{2,3},{4,5}};
  parameter Real[3,2] a={{2,2},{2,2},{2,2}};
  Real[3,2] b;
  Real max;
algorithm
  max:=0;
  for i in 1:3 loop
    for j in 1:2 loop
      b[i,j]:=m[i,j]+a[i,j];
      if (max<b[i,j]) then
          max:=b[i,j];
      end if;
    end for;
  end for;
end matrixAdd;
}}}
It causes the C compilation to break with
{{{#!c
