there is a 1d function with one root in [a,b] intervall, but the solving 
with brent or bisection or ... comes the next error:

gsl: brent.c:74: ERROR: endpoints do not straddle y=0
Default GSL error handler invoked.

It is possible the intervall is to big??
(example:[0,10000]  and the root is about 10)
