Hi
this is a numerical overflow problem introduced by an attempt
to put a Gaussian with a very large exponent onto a rather
coarse grid.
The easy workaround is to increase the cutoff until the NaN's
are gone.

Hi all,
When I use the example regtest-gapw-1/c8_broy_gapw_all.inp to print out the MO_CUBES. It works fine. But if I change the basis set from 6-31Gxx to 6-311Gxx it gave me the cube files with NaNs in it. Have you ever seen this problem or do you have an idea of where is the problem?
