The problem is in lines 3373-3374 and 3382 of
src/sage/schemes/elliptic_curves/heegner.py. The floating point
approximation of the point has x-coordinate 0.500 -
1.32287565553229*I and the code tries to find an algebraic number to
match (i.e. a polynomial over QQ with it as approximate

sage: P = E.heegner_point(-7)
sage: t = P.point_exact()
sage: t.domain()
Spectrum of Number Field in a with defining polynomial x^2 + x + 20
sage: t.domain().base_ring().discriminant()
-79
The answer should be -7 but Sage gives -79
