Question

Here is some code that used to work with my code, but is having a problem now:

#include <iostream>
#include <fstream>
#include <sstream>
#include <cstring>

using namespace std;    
int main()
{
 stringstream out;
 out << 100;
 cout << out.str();
}

I get just blank output. I just changed to snow leopard with Xcode 3.2.

Answer 1

Get this exact same issue under the same conditions Snow Leopard 64-Bit XCode 3.2 Base SDK 10.6 and the switch to Base SDK 10.5 resolves it.

Apparently it’s a SDK 10.6 issue.

and the correct workaround is to remove the preprocessor macros:

• _GLIBCXX_DEBUG=1
• _GLIBCXX_DEBUG_PEDANTIC=1

From the preprocessor settings (or else fall back to SDK 10.5 as above).
