What specific of test 67 may be?
I am using absolutely coorrect methods using
BigInteger and Sturm's theorem and in test 67 we have
situation when
1) (b-a)<1.e-21
2) exist t in (a,b) that p(t)==0
3) exist t1 in (a,b) that d/dtP(t1)==0
4) t!=t1
It Seems that hard to create such test.

Excuse me.
Was bag in polinom dividing.
