  when sine1.y < 0.8 then
      reinit(x, 1);
  end when;
  
  when sine1.y > -0.8 then
     reinit(x ,-1);
  end when;
  
  x = 1;
  
  y = x;
  z = x*1;
  a = x*(-1);
  b = x*2;
end erraticWhenCondition;

What I observed was, x is switching between -1 and 1 correctly, so is y and z. But a and b get constant values of -1 and 2.

So either such an equation should raise an error or the calculation must be done rightly for a and b."	defect	new	high	Future	Backend	v1.12.0		reinit , when
