Comment(by jpflori):
Indeed.
When forcing the call to c_random(), I get
{{{
----------------------------------------------------------------------
| Sage Version 4.8, Release Date: 2012-01-20 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
Loading Sage library. Current Mercurial branch is: mpfr
sage: R=RealField(65)
sage: set_random_seed(42)
sage: R.random_element()
0.9396630990748764761
sage: R.random_element()
0.2987261287446042432
}}}
And with "normal" behavior:
{{{

----------------------------------------------------------------------

sage: R.random_element()
0.3289891249716495404
}}}
So everything looks fine, except for the segfault you got.
Hopefully, I'll provide patches for removing the hackish section and
fixing the doctests tomorrow.
