I can confirm that ahbot causes segmentation faults with Mangos rev9609. I've tried compiling with and without ahbot multiple times, and every time I compile the git pull from Naicisum's repository, Mangos will crash with a segfault after a few seconds of running. Compiling as such works fine though, no errors at all after merging the mangos.conf.dist.in manually.
It used to work fine the last time, when I used the ahbot.patch you posted here in the thread, so I have no idea what could be wrong. GDB says that some thread related to the player.cpp is crashing, but I'm not familiar with debugging C++ and have no idea what this could mean.
