Message #16 received at 33639 <at> debbugs.gnu.org (full text, mbox):
Dear Xorriso hackers,
While building an ISO for i686, running Xorriso 1.5.0 built for i686
(actually ‘grub-mkrescue’, but that’s just a wrapper around Xorriso) in
qemu-system-i386, we end up with an ISO image containing files that lead
to I/O errors (“attempt to access beyond end of device”):

The output of Xorriso and the kernel when it builds the image looks
good.
(More info at <https://issues.guix.info/issue/33639>.)
Using the exact same build process for x86_64 leads to valid ISO images.
Does that ring a bell or would you have advice to further debug it?
Thanks,
Ludo’.
