gdb in QtCreator on windows quits constantly
-
Hello,
I am using QtCreator 4.9, with Qt 5.12.3 and mingw tools on Windows 10. I am trying to debug a nasty issue in my code where the selectionModel of a QTableView is not being updated. When I am in the debugger, I see the reference to my QTableView.I am using the Qt maintenance tool installed Qt libraries, with the QTcreator source pointed to the source installed by the maintenance tool.
Clicking on some of the attributes in the Qt framework objects(QTableView, etc) is like a minefield. Some fields which if I try to expand that just cause gdb to quit with "Unexpected gdb exit" (with the message "the gdb process terminated"). Is there a way to avoid this?
Thanks

This is what I see in my debugger log. I am pasting the parts from a little before the shutdown...

That one looks strange. I'd suggest you to create a bugreport at https://bugreports.qt.io/projects/QTCREATORBUG
Attach the full log and fill out all needed information. You may be asked for a minimal example to reproduce the bug.
In the worst case it's a GDB thing and Creator cannot do anything - but that has to be proved first.
Regards

@JohnGa thanks. for reference, this is the report: https://bugreports.qt.io/browse/QTCREATORBUG-22438

Hi,
I had the same problem with the gdb debugger terminating on entry to a function. (Windows 10 64) Qt Creator 41.2 64 Bit build.
I cleared all of the expressions in the expression evaluator and this got rid of the issue.
There is obviously something wrong with the way Qt and the debugger interact when displaying variables. I have often clicked on a "d" child of an object and had the debugger crash.
Best regards
Rob

How you cleared all expressions in the expression evaluator. I am facing same problem and I think I have to clear it. Beacause it is giving this error only debug mode. So I am not finding way to clear the expressions. Can you guide me please -
@Imran-Hassan
In the left side toolbar, choose "Debug". Then in the "Window" menu, go to "Views", and choose "Reset to Default Layout". Against the right edge, the "Locals" pane will open. Below the "Locals" pane you will see the "Expressions" pane. You can select and clear out all the expressions there.
