Is assignment of braced-init-list to an array correct?


The standard says, under 5.17/9

A braced-init-list may appear on the right-hand side of
- an assignment to a scalar [...]
- an assignment defined by a user-defined assignment operator [..]

While in GCC 4.5.1-pre9999, I can compile this (using -std=c++0x, NOT -std=gnu++0x)

#include <iostream>

int main()
{
        int test[] = {1,2,3};
        std::cout << test[0] << test[1] << test[2];
        test = {4,5,6};
        std::cout << test[0] << test[1] << test[2] << std::endl;
}

and it prints 123456. Is GCC correct here?


Solution

  • It looks like a bug to me. The initialization (int test = {1,2,3};) is fine, but as far as I can see, nothing in the standard allows the assignment.
