Run into "Internal Error: Corrupted BufferExtend"

[huchengjiang]

The decompressor occassionally running into this error. If restart the decompressor (decompressUnordered mode) can continue without the error in the same binary log location.

But it could happen again later, this is killing the quality in production by dumping Text log file.

The error reported from log.cc #2022.

                fprintf(stderr, "Internal Error: Corrupted BufferExtent\r\n");

Has anyone encountered this? Any helpful hints are appreciated.
