Segmentation fault on Comedi_config

Hi all,

 

I am new to comedi. Here I face a problem when I want to configure my
pci-1200 card.

 

I get a "segmentation fault" when I run the "comedi_config /dev/comedi0
pci-1200".

Here I attached a section of dmesg which I think is related.

Can someone help me to find out why this is happening? And is there any
solutions?
