Andrew, this is quite helpful. While it does not pinpoint the actual trouble source, it points to a different abort location. All previous segfaults pointed to a different location (Which I have now checked multiple times and not found any notable problems, just cosmetic things). This strengthens the point it may be related to threading - of course, problematic to troubleshoot.
I'll see how I proceed from here. Again, if some of you that experience the problem could run rsyslogd compiled for single threading, that would be most helpful.
