FIX: An exception occurs when multiple threads call the C run-time "atexit" function at the same time in Windows Embedded CE 6.0 R3

When multiple threads call the C run-time atexit function at the same time in Windows Embedded CE 6.0 R3, an exception may occur. The issue occurs when the code that calls the atexit function is not serialized or when the atexit function is inserted by the compiler.

The issue occurs because the C-Run time atexit function is not made thread-safe, so the memory table that the function uses is corrupted.
