Qt Creator crashes on multi-column selection

I'm using Qt Creator 6.0.2 (based on Qt5) (number 55)

(url: https://download.qt.io/snapshots/qtcreator_qt5/6.0/6.0.2/55/qt-creator-opensource-windows-x86_64-6.0.2_55.exe).

Consider the next piece of code:

01 #include <QWidget>
02 
03 void f()
04 {
05 QWidget w;
06 w.resize({400, 200});
07 w.move(200, 300);
08 }

and particullary lines 06 and 07

if I set the cursor at the end of line 07 and move cursor up holding Alt+Shift (what means multi cursor selection) then editor does not create the second cursor as it expected.

And conversely, if I set the cursor at the end of line 06 and move cursor down holding Alt+Shift then the Creator crashes at all.
