  We are working on a fix.
  
Please update to the current version, see
http://gmplib.org/repo-usage.html.

This fix hasn't been fully tested yet, we will know more after the next
round of automated builds.

We have also improved the test suite; this bug should not have passed
unnoticed.  Further improvements are planned.
