Comment(by zimmerma):
Jean-Pierre,
the test of {{{real_mpfr}}} failed with a Segmentation fault on cicero.
However I get
the following with the "gross hack" on cicero (32-bit Pentium 4):
{{{
----------------------------------------------------------------------
| Sage Version 4.8, Release Date: 2012-01-20 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: R=RealField(65)
sage: set_random_seed(42)
sage: R.random_element()
0.9396630990748764761
sage: R.random_element()
0.2987261287446042432
}}}
and without the "gross hack":
{{{
----------------------------------------------------------------------
| Sage Version 4.8, Release Date: 2012-01-20 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: R=RealField(65)
sage: set_random_seed(42)
sage: R.random_element()
0.7846023201112678858
sage: R.random_element()
0.3289891249716495404
}}}
You should be able to reproduce the later on a 64-bit machine.
