A few questions...

What version of Centos are you running?

What version of the GNU libraries is installed?

What version of ifort are you using?

CentOS 7 (Red Hat 7) is not supported. See the System Requirements.

In the past when I had this problem I replaced the libstdc files from lib directory of Visit with the ones on my system and it

worked. In my case I was ahead of the Visit dstribution.
