Description
I am running QtCreator 5.0.1-1 on Manjaro 5.10.68-1. When opening a big project and waiting a bit the QtCreator crashes with SIGFPE. I ran it in GDB and produced this backtrace:
Thread 12 "Thread (pooled)" received signal SIGFPE, Arithmetic exception. [Switching to Thread 0x7fffb7fff640 (LWP 8621)] 0x00007fffe96f9992 in ??

It seems to have something to do with the tokenizing/lexing of preprocessor statements, so I guess the issue may be specific to the loaded project. If thats the case I have tried opening this project: https://github.com/SerenityOS/serenity
