 On my Mac OS X 10.4.11 (PowerPC), pari gives incorrect results with GMP
 4.2.4 (i.e. with the gmp variant):

 Can anyone reproduce this problem?

 If you have the same problem, do not use the gmp variant of pari.

 Note: I've reported the bug to both GMP and PARI developers. I hope that
 PARI developers will be able to give a simple testcase.
