Exploring *this in "Locals" results in code execution continuation

Breakpoint is inside 

qthread::Thread::run()

as per https://wiki.qt.io/Qt_Creator_ManualTests_DebuggerGdb

When expanding / exploring "*this" in Locals, the execution apparently continues. Then, I assume when threads are reaching "wait" it goes in the endless loop, but "closing" "*this" stops / breaks the execution for a moment.

Idk how to explain it, but here is a video https://qtcompany-my.sharepoint.com/:v:/g/personal/dmitrii_akshintsev_qt_io/EQNu8dlj5HBHinZv-KgCH94Bt2wOBdq2O15QvxI6UTP7DQ?nav=eyJyZWZlcnJhbEluZm8iOnsicmVmZXJyYWxBcHAiOiJPbmVEcml2ZUZvckJ1c2luZXNzIiwicmVmZXJyYWxBcHBQbGF0Zm9ybSI6IldlYiIsInJlZmVycmFsTW9kZSI6InZpZXciLCJyZWZlcnJhbFZpZXciOiJNeUZpbGVzTGlua0NvcHkifX0&e=cj9Dda
