>Description:
C++ I/O doesn't work under AIX as of GCC 3.2.  The following program goes into an infinite loop when compiled with -g and segfaults when compiled with -O1:

#include <pthread.h>
#include <iostream>
#include <fstream>

using namespace std;

int
main()
{
    ifstream ifs("/etc/passwd", ios::in);
    if (!ifs)
        return 13;
    while (ifs.good() && !ifs.eof())
    {
        char s[1024];
        ifs.getline(s, sizeof(s));
         if (strlen(s) == 0)
            continue;
         cout << s << endl;
    }
    return 0;
}
