The leaking %k[3]
comes from the solve_rec function. After looking at it for a few minutes, my first guess is that simplify_sum has supplied only 2 initial conditions to solve_rec, but 3 are needed by solve_rec_ic1 in order to eliminate all three arbitrary constants which are introduced by hyper_poly (called from solve_rec).
So there is some interaction between solve_rec and simplify_sum, but at this point I think the problem is in simplify_sum.

The following seems to be a problem with simplify_sum:
It looks like the %k[3] constant is something that escapes from the linear recurrence solver or so.
