The root cause is incompatibility of glibc from CentOS 6 to CentOS 7. 
It has no relationship with uninitialized buffer.
The right solution is to build trafodion binary using gcc 4.8 under centOS 7 to 
run it on CentOS 7.
So close this jira now.

the problem is not caused by 'uninitialized buffer, the title is not proper. 
Will continue to work on this.
