Fixed generator segfaults on OS X 10.6. Regarding the change to dgenerator.cpp, I am not actually sure if 0 is the correct value to pass, but it seems to work and the code which had been there before was just plain incorrect ? it read past the list boundaries.

import qt.core.QMetaType;

import std.stdio;
import std.conv;
import qt.core.test.Objects;
//import qt.gui.QApplication;

void main(string[] args)
{
    /+
    scope app = new QApplication(args);
    app.exec();
    +/
}
