QtCreator crash on switching between files

I opened my CMake C++ project. From the previous session it had several files opened. I switched to another open C++ file and QtCreator crashed. See the backtrace attached.

The crash happens only when I switch to a particular file. I'm able to switch to other files without a problem. What's interesting, yesterday I was editing this very file in QtCreator and it didn't crash. Apparently, the problem appeared after I restarted QtCreator and it reparsed the project.

I wasn't able to identify the particular piece of code that caused the crash. The code includes quite a few headers, some of them are from Boost and ffmpeg. It kept crashing until I commented this line:

std::unique_ptr< AVFormatContext, xcoder::av_format_context_deleter > m_avf_ctx;

as well as ffmpeg headers. But after it stopped crashing I uncommented all code back and it didn't crash again after restart.
