--- Comment #2 from Paul Zimmermann <zimmerma+gcc at loria dot fr> ---
idem in double precision:
Testing function tan for exponent 0 [seed=17940].
rounding mode MPFR_RNDU:
wrong underflow flag for x=-4.0000000000000@-269
library gives -4.0000000000000@-269
mpfr gives -4.0000000000000@-269
underflow: mpfr 1, library 0
This is the smallest subnormal 0x1p-1074.
