This sample is indeed a case where the retuning of FLAC 1.3.1 
shows a severe regression. It seems the patch does work quite 
well in this case, but it does not fully fix the regression.

Looks like I've missed the talk about this regression introduced in 1.3.1.

Just wondering, the 1.2.1 was similar to 1.3 or better/worse ?

Thanks,
