Is that correct? I cannot find anything > about that in http://doc.qt.io/qt-5/qsharedmemory.html You can find it in the changelog, in the "Impotant Behavior Changes" section. http://code.qt.io/cgit/qt/qtbase.git/tree/dist/changes-5.9.0#n35 - [QTBUG-60771] Reverted a change that caused Qt 5.6 through 5.8 not to connect to QSystemSemaphore and QSharedMemory created by running applications using Qt earlier than 5.6. Unfortunately, this means that Qt 5.9 will not connect to 5.6-5.8. Also, this is on Windows, where we ship one product, and the gmic team ships another product. Which is only called a plugin-because it used to be gimp-specific, where all plugins are in a separate process. -- You are receiving this mail because: You are watching all bug changes.
