This package has never built on s390x. Looking at debian-ports results,
it's probably a big endian architecture issue.

Latest s390x build log is at

https://buildd.debian.org/status/fetch.php?pkg=libxml-hash-xs-perl&arch=s390x&ver=0.56-1&stamp=1613669844&raw=0

Closing this bug with the 0.58-1 upload was too optimistic, 0.58-1
and 0.59-1 have test failures also on architectures were the tests
formerly passed.

This shouldn't go into testing ..


Cheers,
gregor

Version: 0.63-1

0.63-1 looks much better:
https://buildd.debian.org/status/package.php?p=libxml-hash-xs-perl

All release architectures are built, from the ports architectures
alpha still is in Needs-Build, and sparc64 fails with SIGBUS in the
tests.

Closing this bug.


Cheers,
gregor

0.64-1 built on sparc64 as well.

Cheers,
gregor
