I am running probtrackx2 iteratively on a three very similar mac pros.  It is running fine on two of them, but the 3rd one got a mysterious error:

probtrackx2(50846,0x7fffd00973c0) malloc: *** error for object 0x7f83849044d8: incorrect checksum for freed object - object was probably modified after being freed.

*** set a breakpoint in malloc_error_break to debug

/usr/local/bip/bip.sh: line 55: 50846 Abort trap: 6           probtrackx2 -x ${seed} -l -c 0.2 -S 2000 --steplength=0.5 -P 5000 --stop=${inv} --forcedir --opd -s ${BEDPOST}/merged -m ${BEDPOST}/nodif_brain_mask --dir=${tract_dir} --targetmasks=${tract_dir}/targets.txt --os2t

Any insights about why this might happen?  Thanks very much.
