Hi, (corresponding bug report for LaTeX: https://tex.stackexchange.com/questions/585289/corrupt-pdf-with-includegraph... ) when LuaTeX includes a PDF file in which a Page object contains a Metadata stream, then the output is a invalid PDF file since LuaTeX adds the stream inline into the directory instead of adding a reference. plain LuaTeX example: Download page.pdf from https://bitbucket.org/longwayahead/latex-problem/src/master/ and then compile with plain LuaTeX: \saveimageresource{./page.pdf} \useimageresource\lastsavedimageresourceindex \bye The issue can be fixed by removing a single character: In pdftoepdf.c, line 875 a comment correctly mentions that indirection has to be preserved, but for this to work the previous ppdict_rget_obj has to be replaced with ppdict_get_obj to ensure that indirections are not already resolved.
