Monatomic hydrogen crashes double-hybrid DFT

With psi4 v1.3.2, the following input:

molecule H {
0 2
H 0 0 0

memory 32 GB
set reference uks

set basis def2-qzvpp
E = energy('dsd-blyp')

gives the following error:

    $ psi4 -i H.input -o H.bug.output
Traceback (most recent call last):

  File "<string>", line 27, in <module>

    core.set_global_option("BASIS", "def2-qzvpp")
--> E = energy('dsd-blyp')

Is there a workaround?

EDIT: for posterity, I’ve edited the input and corresponding output to be a minimum example to reproduce this bug.

This is fixed in 1.4, and we have no workarounds in 1.3. Our release candidate one is up on conda, and release candidate two is going up, but if you need official releases only, you’ll just have to wait.

And for future, please keep your input files as simple as possible when reporting a bug. The geometry optimization, molden files, and dispersion corrections are beside the point.

Alright, I’ll talk to the administrators about getting a release candidate built in my home directory.

And noted, wasn’t sure if this was a known bug or not.
