Global variable has different addresses in different threads, why?

Question

linux

Good evening! Tell me what's the problem? On x86 Ubuntu 12.04 everything is fine, on CentOS 6.5 64 bit there is a problem with addresses, the global variable has a different address in different threads. Posix streams. I see different addresses in the debugger and printing. Because of this memko does not work correctly.

global variable has different address in different threads

Just global, if it's not TLS, it's unlikely. Show the line with the definition of the variable.
