Thanks, but I admit to being stuck... somewhere around line 320 of
boost/math/tools/roots.hpp there's a NaN being generated for type
real_concept, but not for type long double (and real_concept is just a very
thin wrapper around long double). Can you set a breakpoint at that location
and see what the problem is? It should be the third time through that the
problem occurs.

Many thanks for your help, John.
