This is a failing test case from rtest_orthopoly.mac. The test generates random inputs, and the values above cause a failure. jacobi_p calls hypergeo21, which gives an error interval. The test checks that the exact rational result falls within this error interval. I think that the problem is that there is already some imprecision in the input to hypergeo21. In this case, hypergeo21 is called with 11/12 in the exact version, but the floating point version of (1+5/6)/2 = 11/12 generates 0.9166666666666667d0,...
