The following code snippet is wrongly rejected int main() { sizeof(&main); } --- main.cpp: In function 'int main()': main.cpp:1: warning: ISO C++ forbids taking address of function '::main' --- But the Standard allows that within a sizeof, because according to 3.2/2 it does not constitute a "use" of main.
