Invalid memory reference in MCLR

Hello there,

recently I tried to do a geometry optimization using MCPDFT on a rather large molecule (Mo3S13).
But I encounter a problem in the SLAPAF step that invokes MCLR, resulting in an invalid memory reference.

The same input file has been proven to work for a smaller molecule.
Do any of you have an idea what the culprit could be? The respective input file and output can be found below.
Many thanks in advance!

Input script:

&GATEWAY
  xbas = cc-pVTZ-DK
  ricd
  xyz

 No .RLXPT2  or MCKINT  , I hope that is OK
 Seward mode is assumed, reading perturbation from ONEINT  
 OrdInt status: non-squared
