1.5 to 1.6 ODE Init Val GSL_EBADFUNC


I just switched from gsl 1.5 to 1.6, and now I get GSL_EBADFUNC back
from gsl_odeiv_evolve_apply. 

My model has a step function in it that may turn on mid step. Often this
causes the derivatives to become infinite or not a number.  Whenever
this happens I set the derivatives to 0 and return my own error code,
#define KHH_SILLY_MODEL 65521, from my derivative function.  Then after
gsl_odeiv_evolve_apply returns if status == KHH_SILLY_MODEL I chop the
step size.

Adjusting the derivatives may not be the right thing to do, but
shouldn't my error code make it all the way back out?
