Sorry, this is another feature we need to address in the code with respect to defining a basis set as *. The following input deck works:

start nw
memory stack 600 mb heap 100 mb global 800 mb
charge 0

geometry
O    -0.989 0.6203 0.0827   
H -0.3665 1.1207 -0.4459
H -1.6444 1.259 0.3632
X -0.67775 0.8705 -0.1816
X -1.3167 0.93965 0.22295
end

basis cartesian
O library 6-311++G(2d,2p)
H library 6-311++G(2d,2p)
end

dft
xc pbe0
end

esp
recalculate 
probe 0.07
range 0.3
factor 1
spacing 0.02
end

property
dipole 
quadrupole
end

task DFT property

Yes, this is what I want.
Unfortunately, the replacement from bq to X leads to crash:

OK, I think I see what you want. You want to have the ESP charges at the coordinates represented by the Bqs. This is not the way this should be done. Bq's are considered to be charges and there is a charge expected to go with it. Without a real charge there the code gets confused. However, there is an alternative: Replace bq with X.
