--- Comment #1 from Paul Zimmermann <zimmerma+gcc at loria dot fr> ---
same in double precision:
Testing function exp2 for exponent 0 [seed=4342].
rounding mode MPFR_RNDZ:
wrong underflow flag for x=-3.fe0000000003e@2
library gives 3.fffffffff5418@-256
mpfr gives 3.fffffffff5418@-256
underflow: mpfr 1, library 0
