Volunteering? Not for the bug hunt, not this one. Once someone has figured out where sh** happens we'll talk again.

It seems it's the sole cause, though. Would be easy to verify if cmake had some feature to avoid concurrency of a particular command, but I doubt that exists.

This is a very weird concurrency issue I think. We're talking about independent processes causing each other to crash, so there cannot be direct (= interprocess) memory corruption unless meinproc4 uses shared memory. Seems unlikely (why would it) but easy to verify.
I don't know what XML libs are used here, but I also has my doubts that a widely used XML library would contain a bug in this department that somehow never got noticed.
It might be useful to CC the most recent author(s) who has/ve worked on meinproc4 (KDevelop has this handy "git/annotate" feature for that).

That's what I thought too ...
