Qt Creator (4.10.0-beta1, "From revision 61fcdd0459", prebuilt installer from download.qt.io) crashes when loading some sessions (might be related to the loaded projects).
In the session there's a Qt-CMake-project opened which is loaded when switching to the session. Opening the project and running CMake seems to work, the project tree is displayed correctly. During the subsequent analysis/parsing, a segmentation fault occurs.
The crash seems to occur in CppEditor4::setLanguageFeatures; I've attachted a backtrace.
