Does the standard specify whether static variables are destroyed before or after atexit is triggered?
I've pasted in section 3.6.3 of the standard. Jonathan ---------- 3.6.3 Termination Destructors (12.4) for initialized objects of static storage duration (declared at block scope or at namespace scope) are called as a result of returning from main and as a result of calling exit (18.3). These objects are destroyed in the reverse order of the completion of their constructor or of the completion of their dynamic initialization. If an object is initialized statically, the object is destroyed in the same order as if the object was dynamically initialized. For an object of array or class type, all subobjects of that object are destroyed before any local object with static storage duration initialized during the construction of the subobjects is destroyed. If a function contains a local object of static storage duration that has been destroyed and the function is called during the destruction of an object with static storage duration, the program has undefined behavior if the flow of control passes through the definition of the previously destroyed local object. If a function is registered with atexit (see <cstdlib>, 18.3) then following the call to exit, any objects with static storage duration initialized prior to the registration of that function shall not be destroyed until the registered function is called from the termination process and has completed. For an object with static storage duration constructed after a function is registered with atexit, then following the call to exit, the registered function is not called until the execution of the object's destructor has completed. If atexit is called during the construction of an object, the complete object to which it belongs shall be destroyed before the registered function is called. Calling the function void abort(); declared in <cstdlib> terminates the program without executing destructors for objects of automatic or static storage duration and without calling the functions passed to atexit().
