e2f35fa6842508f6bd9d2343f08a17a2a292fd71 (qt/qtbase/5.12.7)
Apologies that I do not have minimal repro program or other details. This crash has been plaguing us every since we upgraded to 5.12.2 (from 5.4.1), and I haven't been able to figure out a repro for it yet.
I wanted to share the stack trace just in case anyone had seen anything similar or may have any pointers on possible culprits

It's a linux desktop application. Sometimes the crashes seem correlated when the application opens up multiple windows / dialogs, though it doesn't seem to be 100% and definitely doesn't reproduce consistently.
