Created attachment 20923 [details] Example input file for ps2pdf ps2pdfwr device stops with `Command terminated' on Linux when it processes a named ANN pdfmark (key /_objdef {...}). This used to work up to version 9.53.3 and it allowed more key-value pairs to be post-added to the annotation dictionary.
