Hi, For one of my projects ConTeXt LMTX 2021.03.17 17:46 fails with: error (nodes): attempt to double-free glue_spec node 145, ignored mtx-context | fatal error: return code: 1 Unfortunately, when I try to minimize the project, the error vanishes. I guess I have to send Hans the whole project, or are there other possibilities? Cheers, Christoph
