Re: [Bug-gsl] msadams.c:973 aborts with GSL_ESANITY

Hi,

Ok, interesting. So likely it's not GSL optimization issue. What happens 
with a different ODE-solver on OSX?

Also, maybe check that the solver is not making a huge number of small 
steps (stiff problem?).

Not being able to reproduce(?) on Linux suggests something OSX specific, 
some linked math library maybe?
