My bad, I completely failed to notice that delayed evaluation
was a part of the problem. Can you simplify the example to
its barest elements that still provoke the error? Hopefully,
this will provide a clue to what the true as to what the
problem is. (Not having seen the definition of "integral",
I'm wondering whether some failure to initialize y to y0
might have something to do with it ... some missing force
somewhere ... but that's a wild and probably wrong guess).
