Thanks. I see the problem now. I've added the following test case to
test_hyperg.c
/* Bug report from Ivan Liu */
TEST_SF(s, gsl_sf_hyperg_1F1_e, (-26, 2.0, 100.0, &r),
1.444786781107436954e+19, TEST_TOL3, GSL_SUCCESS);
TEST_SF(s, gsl_sf_hyperg_1F1_e, (-26.1, 2.0, 100.0, &r),
1.341557199575986995e+19, TEST_TOL3, GSL_SUCCESS);
