Hi Adrian,
This should be reported upstream, see:
https://github.com/jmacd/xdelta/issues
The testsuite also fails with unaligned access:
https://buildd.debian.org/status/fetch.php?pkg=xdelta3&arch=sparc64&ver=3.0.11-dfsg-1.2&stamp=1757507449&raw=0
I can file the bug report.
That would be much appreciated, thanks!
Interestingly, xdelta3 already contains code to detect and account for
unaligned memory access. There's an m4 script that's supposed to do the
detection (m4/ax_check_aligned_access_required.m4), but it seems like it's not
doing its job correctly.
By putting the following into debian/rules, the script can be bypassed:
override_dh_auto_configure:
dh_auto_configure $@ -- ax_cv_have_aligned_access_required=yes
This makes the bus error go away. The pristine-tar build is still failing, but
this might have other reasons.
Regards,
Gregor
