>Description:
compilation of the following source results in overwriting the char pointer of name. using the second_function there is no problem as well after interchanging the order of the two statements in get_string

include <iostream>
using namespace std;

char* name;
char* ret_string="returned string";


void* first_function(void **data)
{
    *data=ret_string;
}

void* second_function(int *data)
{
    data=0;
}

void* third_function(void **data)
{
    *data=0;
}

void get_string(){
    char* popped_name;
    int number;
    first_function((void**)&popped_name);
    //second_function(&number);
    third_function((void**)&number);
    name=popped_name;
}

main()
{
    cout<<"start test"<<endl;
    name="initial_name";
    cout<<"name is "<<name<<endl;
    get_string();
    cout<<"name is after functions "<<name<<endl;
}
>How-To-Repeat:
this does only fail on the opteron/x86_64
compilation and run will show the last cout not printing name
