-Some global variables defined in external libraries (such as ``++std::cout++``, ``++std::cin++``, ``++std::cerr++``) are acceptable to use, but you should have a good reason to create your own. If you use a global variable, ensure they can be safely accessed concurrently.
+Some global variables defined in external libraries (such as ``++std::cout++``, ``++std::cin++``, ``++std::cerr++``) are acceptable to use, but you should have a good reason to create your own. 
+If you use a global variable, ensure they can be safely accessed concurrently, and there are no issues related to order of their initialization (see S7119).
 
 Remember that it is much easier to maintain software without globals. Instead of such variables, it is better to design functions to take as input all the required variables. In addition to serving documentation, this also helps future refactoring and the evolution of the code.
