Thanks Tushar for the testing.
I further worked on ZSTD and now have implemented client side
compression as well. Attached are the patches for both server-side and
client-side compression.
The patch 0001 is a server-side patch, and has not changed since the
last patch version - v10, but, just bumping the version number.
Patch 0002 is the client-side compression patch.

Thanks, Jeevan, I again tested with the attached patch, and as mentioned
the crash is fixed now.
also, I tested with different labels with gzip V/s zstd against data
directory size which is 29GB and found these results
====
./pg_basebackup -t server:/tmp/<directory>
--compress=server-zstd:<label> -Xnone -n -N --no-estimate-size -v
--compress=server-zstd:1 = compress directory size is 1.3GB
--compress=server-zstd:4 = compress directory size is 1.3GB
--compress=server-zstd:7 = compress directory size is 1.2GB
--compress=server-zstd:12 = compress directory size is 1.2GB

./pg_basebackup -t server:/tmp/<directooy>

--compress=server-gzip:1 = compress directory size is 1.8GB
--compress=server-gzip:4 = compress directory size is 1.6GB
--compress=server-gzip:9 = compress directory size is 1.6GB
