Comment (by chapoton):

 This is now working
 {{{
 sage: sage: e = EllipticCurve('37a')
 sage: sage: K.<a> = QuadraticField(-40)
 sage: sage: A = K.class_group().gen(0)
 sage: sage: from sage.modular.modform.l_series import GrossZagierLseries
 sage: sage: G = GrossZagierLseries(e, A)
 sage: sage: G._dokchister.check_functional_equation()
 2.77555756156289e-17
 sage: sage: G = GrossZagierLseries(e, A**2)
 sage: sage: G._dokchister.check_functional_equation()
 -3.64291929955129e-17
 }}}
 After six years !
