[cfe-dev] GNU extensions - different behaviour of g++ and clang for taking address of temporary array

[Aleksei Sidorin via cfe-dev]

Hi all,

Consider a test case:

#include<stdio.h>

typedefinta[];

voidprint(int*c) {
    printf("%d\n", c[0]);
}

intmain() {
    print(a{2});
return0;
}

`g++ -std=gnu++11 -fsyntax-only` fails to compile this code: "error: 
taking address of temporary array". However, clang accepts it without 
any warnings and there is no any ASan output for it. Could someone 
explain me if it a GCC or Clang issue?
