Ok, running the command:

    src/test_seeking/test_seeking flac_char.ogg
	
resulted in:

    +++ seek test: FLAC__StreamDecoder (Ogg FLAC, read_mode=0)
    
    file's total_samples is 0
    Begin seek barrage, count=0
    #0:seek(0)... seek failed, assuming it was past EOF... OK
    #1:seek(1)... seek failed, assuming it was past EOF... OK
    #2:seek(2)... seek failed, assuming it was past EOF... OK
    #3:seek(3)... seek failed, assuming it was past EOF... OK
    #4:seek(4)... seek failed, assuming it was past EOF... OK
    #5:seek(5)... seek failed, assuming it was past EOF... OK
    #6:seek(6)... seek failed, assuming it was past EOF... OK
    #7:seek(7)... seek failed, assuming it was past EOF... OK
    #8:seek(8)... seek failed, assuming it was past EOF... OK
    #9:seek(9)... seek failed, assuming it was past EOF... OK
    #10:seek(2332)... seek failed, assuming it was past EOF... OK
    #11:seek(2331)... seek failed, assuming it was past EOF... OK
    #12:seek(2330)... seek failed, assuming it was past EOF... OK
    #13:seek(2329)... seek failed, assuming it was past EOF... OK

and so on.

The test file is here:

yep, this is definitely a bug, thanks for the test case.  requires
a tiny fix to the ogg seek algorithm which I will check in tonight.

Oh cool. I was wondering what happened to that issue.
