Hello FreeSurfer Developers,

I am helping a researcher in my department run FreeSurfer on a new computer.  They insist that it should run on FreeSurfer 4.5 because their old system ran that version.  Is the following possible?  We can run FreeSurfer 6.0 fine, but they say there are differences between the versions.  

1) FreeSurfer version: freesurfer-Linux-centos4_x86_64-stable-pub-v4.5.0-full
2) Platform: Ubuntu 18.04.1 LTS
3) uname -a: Linux clps-pb1 4.15.0-64-generic #73-Ubuntu SMP Thu Sep 12 13:16:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
4) recon-all.log: n/a Segmentation Fault - see below
