Have rebuilt everything completely, also removed my config files just to be sure, and I can \
still reproduce this on both machines with both projects :/ Also I've found out that with \
background parsing enabled, it doesn't even matter what I type where. Just entering anything \
anywhere in an open file leads to the crash after a few seconds.
However, the backtrace slightly changed (still the same general area though):

I really hope that helps somehow. Otherwise, if I can help you debug in any way, please let me \
know! I miss background parsing... :/
