Recent betas have introduced a bidi-related problem with register processing. In the following example, compilation generates a recoverable error when register processing has to trim an entry to fit maxwidth. The error is: luatex warning > node filter: error: ...eXt/tex/texmf-context/tex/context/base/mkiv/typo-dub.lua:496: attempt to index local 'stacktop' (a nil value) Removing the maxwidth constraint, or setting it to a much wider value, allows error-free compilation. Without \setupdirections[bidi=on,method=two] there is no problem, but without it RTL texts are not handled properly. This is a recent change; bidi=global worked a few months ago. (I have not tried with LTR text in a default-RTL document). % macros=mkvi \defineregister[Mindex] \setupregister [Mindex] [n=2, maxwidth=4cm, balance=no] \starttexdefinition unexpanded MIndex \dosinglegroupempty\doMIndex \stoptexdefinition \starttexdefinition unexpanded doMIndex #MARKER \def\Marker{#MARKER}% \dosinglegroupempty\doMIndexFull \stoptexdefinition \starttexdefinition doMIndexFull #ITEM \doifelse{#ITEM}{} {\expanded{\Mindex{\Marker}}} {\expanded{\Mindex{\Marker+#ITEM}}} \stoptexdefinition \setupdirections [bidi=on,method=two] \setupbodyfont [libertinus,11pt] \starttext \startparagraph \MIndex{One}{Mairzy doats and dozy doats and liddle lamzy divey} \input jojomayer \stopparagraph \startparagraph סלאם שלום \stopparagraph \placeregister[Mindex] \stoptext -- Rik Kabel
Here is a much-closer-to minimal example. \setupregister [index] [maxwidth=4cm] \setupdirections [bidi=on,method=two] \starttext .\index{Mairzy doats and dozy doats and liddle lamzy divey} \placeindex \stoptext With the \setupdirections line removed, all is well. However, that line is otherwise required. Setting bidi off around \placeindex is not an option either, since some index entries require it. -- Rik Kabel
And shorter still, isolating the problem to something in \limitatetext: \setupdirections [bidi=on,method=two] \starttext \limitatetext {Mairzy doats and dozy doats and liddle lamzy divey} {4cm} \stoptext -- Rik

That allows the compilation to complete, but method=three breaks other stuff. Try this: \starttext \setupdirections [bidi=on,method=three] \rightaligned{(( How is this?} \stoptext (I also see problems with boxes set in the margin where before they were set centered in the textblock, but cannot construct an example yet.) -- Rik
