Source: ruby-ferret
Version: 0.11.8.6-2
Severity: important
User: debian-...@lists.debian.org
Usertags: alignment
Hi!
I've been doing a full rebuild of the Debian archive, building all
source packages targeting armel and armhf using arm64 hardware. We are
planning in future to move all of our 32-bit armel/armhf builds to
using arm64 machines, so this rebuild is to identify packages that
might have problems with this configuration.
A feature of the arm64 kernel is that it does *not* support fixing up
code with broken alignment, so code that might have built and run OK
on our older armel/armhf build machines due to kernel fixups will now
fail.
When building your package, I've found a bus error (aka alignment
fault) on both armel and armhf. The full logs are online at
https://www.einval.com/debian/arm/rebuild-logs/armel/FAIL/ruby-ferret_0.11.8.6-2_armel.log
https://www.einval.com/debian/arm/rebuild-logs/armhf/FAIL/ruby-ferret_0.11.8.6-2_armhf.log
for reference
I've done a quick bit of debugging to find the source of the
bug. Here's a gdb stacktrace and variable printout to demonstrate the
problem.

Ignore the line number 5180 - it looks like gdb is getting the exact
line number wrong. The fault is in the function p_new():
Posting *p_new(MemoryPool *mp, int doc_num, int pos)
{
Posting *p = MP_ALLOC(mp, Posting);
p->doc_num = doc_num;
p->first_occ = occ_new(mp, pos);
p->freq = 1;
p->next = NULL;
return p;
}
MP_ALLOC() has returned a misaligned pointer, and the code following
here therefore is trying to fill things in misaligned too. p->doc_num
is an int, but is not aligned appropriately...
