delay in initial equation

[Christian Schubert]

The test

simulation/modelica/nonlinear_system/nonlinearDelayTest.mos 

fails because delay is not handled properly during symbolic initialization.

According to the specification, delay returns

expr(time–delayTime) for time>time.start +
delayTime and expr(time.start) for time <= time.start +
delayTime

Thus, if I am not mistaken during initialization delay should be simplified to

delay(x, delayTime) = x

[Martin Sjölund]

I'm not sure delay(x,...) should become x during initialization. I always read it as "the start-value of x".

[Lennart Ochel]

And where? I guess x should be fine.
