5179	firstTick operator should return Boolean	eshmoylova@…	somebody	"According to Modelica Specification 3.4, firstTick operator should return a Boolean (Section 16.10):
 This operator returns true at the first tick of the clock of the expression, in which this operator is called. The operator returns false at all subsequent ticks of the clock. The optional argument u is only used for clock inference, see section 16.7.

The following model fails in OpenModelica v1.12.0.
{{{
model M
  Clock c1 = Clock(1,10);
  Boolean dt;
equation
  dt = firstTick(c1);
end M;
}}}
The error given: 
  Type mismatch in equation dt=firstTick(c1) of type Boolean=Real.

If I change the type of {{{dt}}} from {{{Boolean}}} to {{{Real}}} the model simulates but the result for {{{dt}}} is 0 at all times."	defect	closed	high	1.13.0	Frontend	v1.12.0	fixed
