Description (last modified by Víctor de Buen Remiro)

Next code shows how function Excel.ReadCell lost three objects in each iteration.

Real CheckMemoryLeakInCycle (4, Real(Real void)
{
  Real xls = Excel.Open("../test_0001/data.xls");
  Real Excel.ActivateWS(xls,1);
  Anything cell = Excel.ReadCell(xls,[[1, 1]]);
  Real Excel.Close(xls);
  True
});

ouput:

lost objects = 12 in 4 iterations
lost objects by iteration= 3

However Excel.ReadText doesn't lost any object

Real CheckMemoryLeakInCycle (4, Real(Real void)
{
  Real xls = Excel.Open("../test_0001/data.xls");
  Real Excel.ActivateWS(xls,1);
  Text cell = Excel.ReadText(xls,[[1, 1]]);
  Real Excel.Close(xls);
  True
});

ouput:

lost objects = 0 in 4 iterations
lost objects by iteration= 0
