Qt Creator 4.4.0-rc1, Qt Creator 4.4.0
Linux Mint 18.2
Debugging do not start for QNX 6.6 Qt 5.8.0 and QNX 6.6 Qt 5.9.1 kits with Qt Creator v4.4.0-rc1-60-g9a1030c for linux based on Qt 5.9.1 (GCC 5.4.0 20160609, 64 bit).
When you hit F5 to start a simple application in remote Debug mode where you put some breakpoints, the application start but nothing is printed in the Debugger & Log console, the breakpoints are not reached and the application work as usual.
It also appears the messages sent via console.log() in QML are no more displayed in the Application Output but the ones sent via qDebug() from c++ still are.
Even if you try type a command in the Debugger & Log console like
User commands are not accepted in the current state
I also tested with a Linux gcc64 Qt 5.9.1 kit and the Debugging start and breakpoints works.
With Qt Creator 4.2 sharing the same configuration files via command option
The debugging at least start, with the same QNX 6.6 Qt 5.8.0 and QNX 6.6 Qt 5.9.1 kits, messages are printed on the Debugger & Log console, you can type command inside it and breakpoints work.
