This has just been confirmed as to cause a binary compatibility issue. The rule for overriding virtuals is that it's ok, provided the old implementation (namely, QIODevice::open) is still called. That's exactly what happens if you compile Qt Creator with Qt 5.0 and run it with 5.1. Utils::QtcProcess's vtable contains QIODevice::open, so it's like it overrode and used the old implementation. The solution, as I see it, is to modify QProcess::start() to not depend on QIODevice::open. Note: this problem also applies to QLocalSocket. QAbstractSocket is not affected because https://codereview.qt-project.org/43286 did not integrate. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
