looks as if the macro package calls for a direction other than the four implemented ones (TLT, TRT, LTL, RTT).
That is just a side-effect. I have deduced so far, that the problem is that one of internal structures for \halign becomes trashed somewhere in the process. That gives one of the nodes a bad field, which in turn causes a bad attribute assignment to happen, resulting in the assertion failure. Revision 4327 (trunk) adds an assert() so that the actual problem is discovered earlier (but luatex still crashes). Best wishes, Taco
