GTM-Proxy fails with SEG-V

Sudo-san reported me that GTM-Proxy fails with SEG-V.    It runs normally in Ubuntu and without O2 build option, it also runs in CentOS too.   Finally, I found that it only fails with O2 option at CentOS.    It looks that entry to memory allocation handler is corrupted.   I will look into it tomorrow.

It was caused by uninitialized thrinfo, which points to all the memory context.   Just adding memset() fixed the problem.

I checked all the other malloc() in GTM-related code and found all the others are associated with proper initilization or written before read.
