Comment(by hgranath):
If we want to fix only the rational case, that is of course easy to
do. I have two alternative new patches: one for doing just that, and
one which is basically my first patch but reworked to not affect the
case of floating point input (which was an undesired side effect).
With the QQ patch, it is unfortunately still easy to construct cases
that will fail: e.g. binomial(1/2,SR(1)),
binomial(SR(10**20+1),10**20) and binomial(SR(10**7+1),10**7) (the
last one takes a looong time).
