: This is an old problem that has never been fixed.

In the mean time, it is also correct to say that proper symmetry adapted calculation in linear moleculs can be performed
by averaging densities in one symmetryb block, if C2 symmetry is used instead of C2v.
The price is, of course, the size of the calculations.
