I reported this to developers.

High precision did not help. This table shows A and B for m from 20 through 30. The abrupt shortening of B indicates a serious loss of precision.

In[6]:= TableForm[Transpose[{Table[A[m], {m, 20,30}],Table[B[m], {m, 20,30}]}]]

Out[6]//TableForm= 0.419886555129855029654837453844 0.41988655512985502965483745384
