In the last couple of months we have gotten two crash reports of our application, getting a 'divide by zero' in QTextEngine::shapeText.
Our application is on macOS, Windows, and Linux, and we have only seen this on macOS.
I've attached the two crash reports.
Our app has been running on Qt 5.15 this whole time. I recently (mid December?) updated to the latest tqtc commercial Qt 5.15, which was essentially 5.15.8. We've never had this exception before, so I'm wondering if it's something that was introduced recently.
