Rollback Creator version?
Yesterday, I upgraded to 4.8.0 via Maintenance tool. Now I stumbled upon QTCREATORBUG-21655, which effectively prevents me from working.
How could I downgrade Creator to the last good version?
EDIT: Easier than expected. Could install 4.7.2 side-by-side, it even takes the session information and settings.
Another option - disable clang code model in Qt Creator plugins. It will use the old, built-in code model instead. You can find plugins in Help -> About Plugins...
Seems to be a general clang issue (independent of Creator version), but hard to reproduce. I found a workaround by typing out the full code line in an external editor, then copying it into Creator. Clang seems to take offense at certain code fragments.
The older version can be found at https://download.qt.io/official_releases/qtcreator/4.7/4.7.2/
