I can try to boil it down to some simpler sequence. The crash occurs with some larger package I've been working with where reverting buffers did not quite work the way it is supposed to. At some point I ended up with the situation that reverting a buffer reproducibly crashes emacs. Yet it could well be the case that the real cause is only loosely related to reverting. If I don't succeed with pinning this down, I'll post the whole code so that someone more knowledgeable can look into this. Any hints on what these crashes are possibly be related with according to the backtrace are greatly appreciated. Roland
