Bug#731806: debian-installer: FTBFS on sparc: genisoimage errors

Ouch.
I have no Debian of arch "sparc" in reach.

Valgrind on Linux accuses xorriso-1.3.2 of a small memory leak
with such a run, but not of memory problems.

That would rather be a C compiler problem then.

But given the strange error message of genisoimage, this may
well be a local filesystem peculiarity which causes a chain
of bad memory access with more or less random end.


> 3- Fix the xorriso for alignment problem

I would love to get this done.

Can you get me a stack trace ?

Can you run it with valgrind and send me the message output ?

If the failing machine is not the one which compiled xorriso
from the libisoburn source package, can you try with
  wget http://www.gnu.org/software/xorriso/xorriso-1.3.2.tar.gz
  tar xzf xorriso-1.3.2.tar.gz
  cd xorriso-1.3.2 && ./configure && make
  abs_path=$(pwd)
Without need for superuser or installation try:
  cd ...where.appropriate...
  "$abs_path"/xorriso/xorriso -as mkisofs ...above.options...


Have a nice day :)
