Or in the cddce1 dump:
Analyzing # of iterations of loop 1
exit condition [p_4(D), + , 1](no_overflow) != 0B
bounds on difference of bases: -18446744073709551615 ... 0
result:
# of iterations -(long unsigned int) p_4(D), bounded by 0
Found loop 1 to be finite: iterating -(long unsigned int) p_4(D) times
where we might be able to construct a testcase with an infinite loop and
no side-effects that CDCE will then remove.
