I regularly run a flac -t check for my music collection. After upgrading from version 1.3.4 to version 1.4.1 (1.4.0 is also affected) some tests fail with FLAC__STREAM_DECODER_END_OF_STREAM that where ok before. Only a minority of my files are affected. Most of them are still returning OK as test result. This happens for the complete Album at once, i.e., if one file on an album is affected every other file on the album is affected as well. Thus, this might has to do with specific encoders or parameters of the encoder. I am running a Linux build using the gentoo packages of flac. Since the files have a copyright I cannot upload an afffected file here. However, I am willing to execute further tests if needed. $ flac -t 01\ -\ Tomzen\ -\ Namaste.flac flac 1.4.1 Copyright (C) 2000-2009 Josh Coalson, 2011-2022 Xiph.Org Foundation flac comes with ABSOLUTELY NO WARRANTY.
