[Flac-dev] Problem moving to 1.1.3

[Aaron Graham]

I'm working on an embedded product, upgrading it from 1.1.2 to 1.1.3.
I'm getting lousy compression for FLAC files that are encoded with
1.1.3 (integer only).  The resulting FLAC files still sound correct
and will decode properly, but are only compressed about 10% even when
compressed at the highest level (I get about 40% compression with the
same files in 1.1.2).

Here is a typical slice of a poorly compressed file:

There are a lot of 0's in there.  Encoding the file with 1.1.2 gives
entirely different results, with no noticeable patterns or long
strings of 0's.  My encoder is a stream encoder, as opposed to a file
encoder, but of course, it's always been that way.

Anything come to mind?

Thanks in advance.
