After switching from Creator 4.7 to 4.8 every file I open causes clang code model to fail and restart indefinitely:
Clang Code Model: Error: The clangbackend process has finished unexpectedly and was restarted.
The terminal shows some more information from a qWarning:
Error in ClangCodeModelServer::documentsClosed: Document 'some_source.cpp' does not exists!
terminate called after throwing an instance of 'std::invalid_argument'
The error goes away when setting `LC_ALL="C"`, which affects the behavior of 'stod'. My default locale apparently uses "," as decimal separator.
