empty_argv is no longer static in Python 3.8, but it is declared in a temporary scope, whereas argv keeps a reference to it. empty_argv memory (allocated on the stack) is reused by make_sys_argv() code which is inlined when using gcc -O3. Define empty_argv in PySys_SetArgvEx() body, to ensure that it remains valid for the whole lifetime of the PySys_SetArgvEx() call. (cherry picked from commit c486825)
