--- Comment #3 from Paul Zimmermann <zimmerma+gcc at loria dot fr> ---
idem in double precision for j1:

Testing function j1 for exponent 0 [seed=14309].
 rounding mode MPFR_RNDN:
      wrong underflow flag for x=-1.8000000000000@-268
      library gives -c.0000000000000@-269
      mpfr    gives -c.0000000000000@-269
      underflow: mpfr 1, library 0
