Comment (by jdemeyer):
Another different regression:
{{{
def test(RR):
for d in range(-20,0):
if abs(RR(quadratic_L_function__numerical(1, d, 10000) -
quadratic_L_function__exact(1, d))) > 0.001:
print "Oops! We have a problem at d = ", d, " exact = ",
RR(quadratic_L_function__exact(1, d)), " numerical = ",
RR(quadratic_L_function__numerical(1, d))
time test(RealField(50))
}}}
From 3.0 seconds in sage-5.7.beta0 to 4.2 seconds with #12215 + #12313.
