Comment (by zimmerma):
with MPFR configured with {{{--enable-assert}}} within sage-5.0.beta9, I
can simplify the
problem to:
{{{
sage: RIF(1,1)
get_exp.c:29: MPFR assertion failed:
((x)->_mpfr_d)[(((((x))->_mpfr_prec)-1)/(64 - 0)+1)-1] & ((~(mp_limb_t)0)
^ ((~(mp_limb_t)0) >> 1))
}}}
This means that we compute the exponent of a number which is either NaN,
infinite or zero.
I will continue to investigate.
