In 4.0.alpha0, this causes a segmentation fault: ---------------------------------------------------------------------- | Sage Version 4.0.alpha0, Release Date: 2009-05-15 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: K.<a>=NumberField(x^2-x+22) sage: w=-13*a-14 sage: E=EllipticCurve([0,0,0,0,-1728*w]) sage: P1 = E.lift_x(-3*a-66) sage: P2 = E.lift_x((-21*a-93)/4) sage: P2.division_points(19)
------------------------------------------------------------ Unhandled SIGSEGV: A segmentation fault occured in SAGE. This probably occured because a *compiled* component of SAGE has a bug in it (typically accessing invalid memory) or is not properly wrapped with _sig_on, _sig_off. You might want to run SAGE under gdb with 'sage -gdb' to debug this. SAGE will now terminate (sorry). ------------------------------------------------------------ John --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
