[Freesurfer] segmentation fault during make_average_surface

Hello,

I'm trying to make an average surface using the latest version of make_average_surface (2005/08/02 19:14:20 nicks Exp), and I got the same error as posted in the following message: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg01135.html, with a segmentation fault when mris_average_surface is called (I get the same segmentation fault when running mris_average_surface alone):

mris_make_average_surface -i 7 -o orig rh orig_avg sphere.reg average_test subj1 subj2 processing subject subj1... The following must be revisited******************************************* Segmentation fault

I did not find in the mailing list how to solve this, thank you very much for your help,
