These are the errors I get with gcc when I compile your code - I made a
few changes i.e. made it a read non POD class.

clcpp_t6.cpp: In function `int main()':
clcpp_t6.cpp:20: error: jump to case label
clcpp_t6.cpp:16: error: crosses initialization of `A obj'

The errors should be self explanatory.

#include <cstdio>

class A
{
public:
int i;
A() : i() {}
};

int main()
{
switch(1)
{
case 1 :
// {
A obj;
std::printf("case 1\n");
// }
break;
case 2 :
A obj1;
std::printf("case 2\n");
break;
}
}
