Hi,
there seem to be problems within gsl_sf_bessel_Jn and gsl_sf_bessel_Jn_array:
- for n<168 they do not return exactly the same results.
- for n=168 only gsl_sf_bessel_Jn returns successfull
- for n>168 both routines return with errors (e.g. in airy.c)
some example code (c++) is attached.
Kind regards
Arvid Requate

Thanks for the bug report. We'll look into it
