Hi, For those of you that know how: can you please check out revision 4032 of luatex and test it on any files you have that contain complicated alignments (latex tabular / context starttable ?). Especially, the bug symptom is an error of this form: ! Emergency stop. <recently read> \endtemplate I have tried various files I do have and it seems that the bug is fixed now, but my file list is not exhaustive (most of my documents use context \starttabulate) Thanks in advance, Taco
