mapping of zero crossings to equations does not work properly

[Lennart Ochel]

The mapping from zero crossings to equations does not work as soon as a model get split up into various equation systems (partitioning). The zero crossing contains only a equation index but no information about the appropriate equation system. The issue can be reproduced using the following model:

model test1
  Boolean a;
  Real b(start=0.7, fixed=true);
equation
  der(b) = if b > 0 then -1 else 1;
  a = time < 0.5 or time < 0.6;
end test1;

The debugger pinpoints to a = time < 0.5 or time < 0.6 instead of der(b) = if b > 0 then -1 else 1. If both equations get reordered the debugger pinpoints to the correct equation.
