[Auto mailings of changes to Lily Issues via Testlilyissues-auto]

Something very weird's going on.

If I redo the definition of \bar "" in a ly-file with a not empty string, which can be done with:

\version "2.21.0"

#(add-bar-glyph-print-procedure "x" (@@ (lily) make-empty-bar-line))
#(define-bar-line "x" "x" "x" #f)

<<
  { c'2 \bar "x" }
  { d'2. }

then all is fine.
Why?

But using an undefined BarLine will cause the bug:

<<
  { c'2 \bar "y" }
  { d'2. }
>>

Why?

And it doesn't fix Simon's example.
