Description
I have a widgets based desktop application running on Windows 10 that utilizes the BLE support of Qt to communicate with a custom hardware through Bluetooth. After running the application for some time - involving active Bluetooth communication in the background - the following assert is being triggered:
The call stack of the fault is the following in Visual Studio:
Qt5Cored.dll!qt_message_fatal(QtMsgType __formal, const QMessageLogContext & context, const QString & message) Line 1875 Qt5Cored.dll!QMessageLogger::fatal(const char * msg, ...)
