[Freesurfer] (FSv6 dev) recon-all -base ERROR: segmentation fault

Hello FreeSurfer Developers,

We have been testing a dev version of Freesurfer version 6 (freesurfer-Linux-centos4_x86_64-dev-20160405)

Cross-section runs were successful without any error but we have been getting a segmentation fault error while trying to generate the base image for longitudinal processing.

The recon-all.log from base image generation run is attached.

The command line used is: recon-all -base ABE4869G-1307-base -tp ABE4869G-1307-1 -tp ABE4869G-1307-2 -tp ABE4869G-1307-3 -tp ABE4869G-1307-4 -all

Is there a change in the syntax in version 6? or is this a bug in the dev version we have been testing?

Thank you
