This might be compiler optimization issue. Can you please try with non-optimized (-O0) version of GSL? I have no idea how to get that with macports... Alternatively, can you try to run your program on Linux?
Strangely, if I solve the ODE with and abstol of 1e-8 and then immediately afterward solve again with an abstol of 1e-10, (for convergence testing) then the abort happens (call this case 1).
How exactly do you "immediately afterward solve again"? Do you call gsl_odeiv2_driver_reset in between calls to gsl_odeiv2_driver_apply?
