The following model can't be simulated in OMShell:

end TestModel;

There are 25 values shown in the OMShell but only 24 are excepted.

This works better since doubles have rounding errors in them, but I guess Per will have a look and try to fix the initial problem (in this version you will also get 0.0 as an element, yours gave -0.00000000000000005551115123125783):

model TestModel
  Real Variable1[25];
equation 
  Variable1 = {0.1*i for i in -24:2:24};
end TestModel;

Fixed in r13016, real ranges are now a bit more robust with regards to rounding errors.
