Flagging this as a blocker as it breaks SQL execution.

affects me too, same description.

can not be reproduced here on the latest master (Linux).

I don't understand why it happens on Windows, maybe converting
the QRegExp to str might helps ??

If you can give at it a try apply the following patch (I cannot test on Windows just guessing here)
