There seems a bug in the function “gsl_sf_hyperg_1F1" in version 1.16.

See the attached test program, in which the generated value is correct when ri=1000 while is wrong when ri is large (ri=4000 in the program).
The result was compared with Mathematica.

When I tried version 1.9, which somehow gives the correct result.
However I am not sure how this happens in
