Comment(by jdemeyer):
There is a doctest failure on a 32-bit machine:
{{{
sage -t -long "devel/sage/sage/schemes/elliptic_curves/heegner.py"
**********************************************************************
File
"/Users/jdemeyer/sage-4.6.alpha2/devel/sage/sage/schemes/elliptic_curves/heegner.py",
line 3048:
sage: P = E.heegner_point(-19); y = P._trace_numerical_conductor_1();
[c.real() for c in y]
Expected:
[-1.26165722088693e-16, -1.00000000000000, 1.00000000000000]
Got:
[-1.26126537554300e-16, -1.00000000000000, 1.00000000000000]

}}}
When this is fixed (just write -1.261...), this ticket can finally gets
its positive_review.
