Do you have some basis for doubting the correctness of the Risch algorithm? (Risch's work is described in a long paper in Transactions of Amer. Math. Soc. and a shorter one in Bull. Amer. Math. Soc., both around 1969-70. It's been a while since I've looked at those; I did not check all the proofs myself.)
