Comment (by cremona):
With Sage 5.9 I get
{{{
----------------------------------------------------------------------
| Sage Version 5.9, Release Date: 2013-04-30 |
| Type "notebook()" for the browser-based notebook interface. |
| Type "help()" for help. |

sage: set_random_seed(27)
sage: sage: p = random_prime(2^384)
sage: sage: a = GF(p).random_element()
sage: sage: b = GF(p).random_element()
sage: sage: E = EllipticCurve(GF(p),[a,b])
sage: sage: pari("ellap(%s,%s)"%(E._pari_init_(),p))
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call
last)
<ipython-input-6-1b990fd69ca7> in <module>()
----> 1 pari("ellap(%s,%s)"%(E._pari_init_(),p))

in sage.libs.pari.gen._pari_trap (sage/libs/pari/gen.c:56037)()
RuntimeError: _pari_trap recursion too deep
}}}
and I wonder if this still happens with the new pari version currently
being tested?
