flac -t shows FLAC__STREAM_DECODER_END_OF_STREAM since version 1.4.0 for some files

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.

Reproduce the report with 01 - Tomzen - Namaste.flac using flac -t from versions 1.3.4 and 1.4.1, and inspect the metadata with metaflac --list as shown. Compare the decoder results and establish a regression test using an affected file or equivalent fixture; done means valid files no longer report the 1.4.x error while genuine stream errors remain detectable.
