Re: SBE fix gives different result with shntool & flac front-end?

Using a hex editor I compared the two resulting WAV versions of track 04. The shntool-fixed version contains 448 zero bytes (112 samples). The FLAC-fixed version contains about 224 zero bytes, but then about 224 bytes containing data at the very end. So this seems to be a bug in FLAC.

The above tests were done using FLAC 1.1.1. I don't have the latest version installed (1.1.2) to test with, but the "changelog" for v1.1.2 doesn't mention any bugs regarding the --sector-align option.

Is anyone able to do a similar test using FLAC 1.1.2?
good find 4candles. i'll do some test with flac 1.1.2 when i get home.
