      Description

      Hi, developers, thank you for your checking. Does it seem the lock ctrl_mutex is not released correctly when writing to the destination stream fails and writing to the destination stream fails in the compress_write?

      This is similar to the lock data_mutex, which is acquired in a nearby place. It is not released when writing to the destination stream fails and writing to the destination stream fails in the compress_write.

      Thank you for your checking!
