gcc version 4.2.1 (Debian 4.2.1-3)
System: debian-installation from knoppix 5.1.1

When optimizations are turned on (-O, -O1, -O2, -O3),
two or more threads don't recognize when the value of a global variable
changes.
It doesn't matter if it's a global variable or a pointer to a local variable.
The change of its value by thread no 1 will not be recognized by thread no 2.
