Streaming issue "No space left on device" in lrzip 0.651

[stevenshiau]

We encountered an issue when using lrzip to compress the stdin data and output to a file. It gave an error "No space left on device". However, we are very sure the disk space is enough.
It's on Debian Sid live system. If we switched to lrzip 0.641, this issue was not reproduced.
More information is provided in the following.
If you need more info, please let me know. Thanks.
