More on this: I have tracked it down to an empty glyph. When processing the following markup:
(#<procedure bracketed-y-column-markup (layout props indices args)> (1 1) ((#<procedure line-markup (layout props args)> ((#<procedure number-markup (layout props arg)> 6) (#<procedure smaller-markup (layout props arg)> (#<procedure raise-markup (layout props amount arg)> 0.6 (#<procedure musicglyph-markup (layout props glyph-name)> accidentals-2))))) (#<procedure line-markup (layout props args)> ((#<procedure simple-markup (layout props str)> ) (#<procedure smaller-markup (layout props arg)> (#<procedure raise-markup (layout props amount arg)> 0.6 (#<procedure musicglyph-markup (layout props glyph-name)> accidentals-0))))))) The second argument is a line-markup with two arguments. he first is an empty string, which ends up being an empty stencil. The second is based on accidentals-0, which creates a non-empty stencil, but with an empty box. This is due to name_to_index failing for accidentals-0. Much later, ly:stencil-moved-to-edge fails due to having an arg "second" which has an empty extent. (Fails in Stencil::moved_to_edge.) My guess is that either name_to_index failing on accidentals-0 is incorrect, or using accidentals-0 in the first place is incorrect.
