Gandl, can you run MCServer under GDB and do some initial analysis for me? Here's a link to a thread that describes how to do it: ("Reporting crashes on Linux"):

Since you're running on special hardware, it is vital that you perform either Live or Post-mortem analysis for that report, I cannot do much without it.
Also, "Assertion" means that you are running a debug version of the program. Is that your intent, or is that by accident? If you want just to try it out and play on the server, it's better (faster, uses less memory) when you compile a release version, by using "make release=1" instead of "make" during the build process (details are in the wiki: http://mc-server.org/wiki/doku.php?id=compiling_gcc )
I have seen such a crash when the Classic fluid simulator was used, but in the revision that you're using the simulator has already been thrown away, so it's probably a different cause.
