Package: xorriso
Version: 1.3.2-1
Severity: important
Tags: d-i
Dear Maintainer,
I was trying to check if xorriso was usable for building the debian-installer
package.
Unfortunately, using xorriso as replacement for genisoimage leads to a SIGBUS
error.
Seems to be an unaligned access on sparc which is quite picky about aligned
access.
Here's the report from gdb:
