    Description

      I using Ubuntu 15.04 with Qt 5.4.1 (from repo) and GCC 4.9.1.
      When I running the following example code, then I get a segfault:

      #include <QStringBuilder>
...

QTextStream(stdout) << [] {
            QString a('a'), b('b');
            return a % b;
        }() << '\n';

      But if I replace the '%' with '+', the problem is gone.
      Is this a bug or something else?
