Exit code 255 on Windows is a sign of crash. It would typically correspond to 134 (128 + SIGABRT) or 139 (128 + SIGSEGV) on Linux.

This is a test for MDEV-18025. It revealed wrong usage of a zlib function, which would cause failures depending on zlib version, and was subsequently fixed by me as a follow-up commit to MDEV-18025.

Unfortunately, we do not save the output of failed the command anywhere, and it seems nontrivial to modify the test to output the log in case of befailure.

An educated guess is that this failure might be a duplicate of MDEV-14192, which occurs every now and then on mariabackup tests.

Could be related to MDEV-14192. So assigning to vlad.lesin
