Description

the dcheck isn't the right way to handle this case.

  // Read in the compressed data
  uint8_t* compressed_data;
  int bytes_read;
  stream_->GetBytes(compressed_len, &compressed_data, &bytes_read, &status);
  RETURN_IF_ERROR(status);
  DCHECK_EQ(compressed_len, bytes_read);
  eos_read_ = stream_->eosr();
