11532,toms748_solve produces -nan when evaluating a smooth function in a fixed interval,Ola Skavhaug <ola@…>,John Maddock,"In my algorithm that is finding the point where two gamma gamma distributions crosses, the toms748 solver produces a -nan value for the evaluation point. The behaviour occurs quite rarely, and only for extremely specific values of the governing parameters. I have not checked if the problem is cross platform.

I see that the solver evaluates the same point twice, and suspect that the subsequent calculation of the change of the evaluation point somehow divides by 0.

A minimal example is enclosed.
