Description
GIVEN qt5.git project open with qtactiveqt at 6.9 beta 2 (ie. pre https://codereview.qt-project.org/c/qt/qtactiveqt/+/620466), qaxwidget.h open in the editor
WHEN copying the #ifndef QT_NO_DATASTREAM block from outside the class to just before the }; of the class, hitting CTRL-I to re-indent, replacing inline with friend, placing the cursor on the operator>>, hitting ATL-Enter and selecting "Move defintition to qaxwidget.cpp".
THEN QtC hangs with 100% CPU for a few minutes. Attaching gdb to get a backtrace gives
