Comment (by johnmaddock):

 Can you try the attached patch?  I think it fixes this and gives somewhat
 more sane results in the corner cases.  Note however that it's still not
 possible to round trip in the general case - particularly when the
 probability is very close to 1 (within a few epsilon) as in that situation
 there may be multiple values for the random variable which all give the
 same CDF value.
