[Bug c++/25735] New: Assignment operator broken with multidimensional array strings.

[dtrebilco at gmail dot com]

I am not sure if this is correct C++ code anyway, (so please correct me if not)

#include <stdio.h>
#include <string>

using namespace std;

struct TestStruct
{
  string testStr[2][2];
/*  
  TestStruct &operator= (const TestStruct &src)
  {
        testStr[0][0] = src.testStr[0][0]; 
        testStr[0][1] = src.testStr[0][1]; 
        testStr[1][0] = src.testStr[1][0];      
        testStr[1][1] = src.testStr[1][1];      

        return *this;
  }
*/  
};

int main()
{
  TestStruct a, b;
  a.testStr[0][0] = "1234567890";        
  b = a;

  printf("Done \n %s", b.testStr[0][0].c_str());
  return 0;     
}

With no assignment operator, the default generated one causes a "double free or
corruption" error. Single arrays work fine, but I am also unsure what the
correct C++ behaviour should be in this case.
