> Unfortunately, there seems to be some incompatibility between the new
PARI (2.4.3.svn-12577.p4 / Sage 4.6.prealpha3, see #9343 and
[http://wiki.sagemath.org/NewPARI the NewPARI Wiki page]) and MPIR 2.1.1:
> On Ubuntu 10.04 x86_64 (Core2, gcc 4.4.3) exactly two of all doctests
({{{ptestlong}}}) '''segfault''' (in
{{{sage/schemes/elliptic_curves/ell_point.py}}}).
> On Fedora 13 x86 (Pentium 4 Prescott, gcc 4.4.4) the same two doctests
and another one in {{{ell_rational_field.py}}} segfault, and in addition
one doctest in the latter file raises an unexpected exception
({{{TypeError}}}), which seems to be the result of some other failure.
This is due to the new PARI using undocumented features of GMP (that MPIR
doesn't support). and is now addressed at #9837.
