Sadly, as a volunteer operation, sometimes messages get lost in the
cracks. (Actually, this happens with proprietary software too, n'est
pas?) Feel free to just bump a message in that case - it should get
addressed *if* anyone has any clue, which sometimes will not be the
case.
In this case, you have
sage: integrand
0
because it simplifies to zero. But zero as a symbolic expression has
sage: integrand.variables()
()
which is probably responsible for this problem, since the following
lines occur in the code to handle the non-symbolic zero.
if not callable(func):
# handle the constant case
return (((<double>b - <double>a) * <double>func), 0.0)
I don't have time to file a ticket for this, but hopefully someone
will - or you can do so yourself! It should be easy to check for this
case.
Best,
