Hi Sai Pranav, Thanks for the review and testing!
Attached is v3, rebased on current master. I renamed the test to 015_checksum_helper, as 014 is now taken by 014_vm_truncation too. The code is unchanged from v2. The pg_combinebackup suite passes with both Autoconf and Meson on Linux aarch64, with assertions, debug and OpenSSL enabled. The pg_verifybackup leak you pointed out can be addressed separately. Best regards, Yuriy
