There is an abundance of << >> (due to tags being in play) already. My problematic code uses utility functions using ly:context-output-def; the "minimal example" just uses some similar elements until something strange appears, but the strangeness is not really in any remotely recognisable way related to the problem I am seeing. So I cannot really "reduce to a minimal example" sensibly until ly:context-output-def has made it upstream which will be in a few days. -- David Kastrup
