segmentation error

Dear NMAD users,

I am trying to carry out a metadynamics simulation with collective
variables module, version 2012-03-23 as implemented in NAMD 2.9 for
Linux-x86_64-multicore-CUDA on a 32 core workstation running with centos 7
with an nvidia gtx 750; the simulation immediately stops, or does not even
start, with a segmentation fault message appearing on the command editor.
If I try to start a simulation with the same config file without the colvar
module the simulation seems to proceed fine. Does anybody have any
suggestions?
Reported below are the files of the simulation.

segmentation fault:
