Windows 7, Clang 3.9.1 that was shipped with Creator.
Description
I'm using the Clang Code Model.
Sometimes Qt Creator just hangs without any special reason.
I attached a debugger when it happened, and I see:

This is a release+symbols build, so everything is optimized out. I can't get anything from 'this'.
