Broken table-interpolation?

[HansOlsson]

Consider the following:

model Unnamed
  Modelica.Blocks.Sources.CombiTimeTable combiTimeTable(
    table=[1,10; 1,11],
    smoothness=Modelica.Blocks.Types.Smoothness.ConstantSegments,
    verboseExtrapolation=true)
    annotation (Placement(transformation(extent={{-38,-52},{-18,-32}})));
  Modelica.Blocks.Sources.CombiTimeTable combiTimeTable1(
    table=[1,10; 1,11; 2,12],
    smoothness=Modelica.Blocks.Types.Smoothness.ConstantSegments,
    verboseExtrapolation=true)
    annotation (Placement(transformation(extent={{-40,20},{-20,40}})));
  annotation (uses(Modelica(version="3.2.3")));
end Unnamed;

As far as I can see combiTimeTable.y generates 11, 10 as signals, and combiTimeTable1.y is 11, a short dip and then 11, followed by 12 and then linear interpolation.

Setting extrapolation=Modelica.Blocks.Types.Extrapolation.HoldLastPoint gives correct result for combiTimeTable1 - but combiTimeTable is stuck at 10.

One issue is in ModelicaStandardTables_CombiTimeTable_nextTimeEvent - if called at time=1 for this case it can compute nextInterval=1; whereas the expected output would be DBL_INF. (I think.)
