--- Comment #2 from Paul Zimmermann <zimmerma+gcc at loria dot fr> ---
> This also affects functions such as exp10 and exp10f that call exp.
yes, for example in single precision:
Testing function exp10 for exponent 0 [seed=11871].
rounding mode MPFR_RNDZ:
wrong overflow for x=f.fffff0@31
library gives @Inf@
mpfr gives f.fffff0@31
