Hi all, Thanks in advance for your help, and sorry for the slow reply. I've created a small OS X example project <https://drive.google.com/file/d/0B8vFUUth7NpvRFI0MmI2bVJNNEU/view?usp=sharing> that reproduces the issue. (I've run into the size limit for emails on this list so I've put it on Google Drive.) The program just initializes a libFLAC++ stream decoder for a given file and attempts to seek to frame 0. All I've done to the libFLAC code is add a few print statements that make it clear where the failure is happening. The file 'fails.flac' demonstrates the issue. The file 'succeeds.flac' is in the same format but can seek successfully to 0.
I'm running Xcode 8.1 on OS X 10.11.6. We have also seen this issue on iOS. Please let me know if you need any further information (or if anything is wrong with this example), and thanks again!
