Hi, I found a deadlock in Scene.cpp. The problem exhibits itself when calling std::exit() instead of standard way of terminating of the application.
The deadlock is seen on Windows only. On Linux, I get sigsegv or, at least, valgrind gives me info about using already freed memory. After the investigation, I found that the problem is using of static variables in getSceneCache() and getSceneCacheMutex() in Scene.cpp. The destructors of these static variables are registered by the compiler (gcc) using atexit() approach. (I could not believed it and made additional tests, but all the same.) As a result, the mentioned variables are destructed too early and before all global variables, resulting sigsegv and deadlocks... I moved the static variables to global scope and the problem disappeared. Is it the correct fix of the problem? Should I submit a patch? Comments? Ideas?
