"freeze atomic" plus no valence electrons crashes CCSD


Gets Around
Crashes:

start mgplusplus
charge 2
geometry units angstroms
 Mg       0.0  0.0  0.0
end

basis
 * library cc-pvdz
end

ccsd
 freeze atomic
end

task ccsd(t) energy


Works:

start mgplusplus
charge 2
geometry units angstroms
 Mg       0.0  0.0  0.0
end

basis
 * library cc-pvdz
end

task ccsd(t) energy


You also get a crash with CCSD instead of CCSD(T). A TCE-based CCSD(T) run also crashes under the same conditions. Surprisingly, a TCE-based CCSD run does not crash! This works:

start mgplusplus
charge 2
geometry units angstroms
 Mg       0.0  0.0  0.0
end

basis
 * library cc-pvdz
end

tce
 freeze atomic
 ccsd
end

task tce energy
