Segmentation fault when running XtraBackup version 2.2.6 and 2.2.7

I’m getting a Segmentation Fault when running XtraBackup on MySQL 5.5 with both v 2.2.6 and 2.2.7 on CentOS. I tried using a trusted and true script, it failed. used another, it failed. Tried manually to just run it and it failed.

I’ve not experienced this before.

can you please provide the exact command you used for the backup along with backup log complete output. Also, please provide the my.cnf file to identify possible cause of this problem.
