Something went wrong in that area.

I don't understand C++ and Linux well enough, so it's hard for me to find the cause of the crash. As I understand it, the reason is that event->wd passes an invalid file descriptor, but I don't understand how.

Maybe you can help me to figure out this issue. It happens once per 2-3 months, hard to detect/reproduce.
