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

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

Sebastien's machine now has a xorriso-1.3.7 (the current development
snapshot) with changed libburn/async.c.

The callers of add_worker() now declare:

        union w_list_data o;

rather than

        struct union_member o;

The type of the fourth parameter of add_worker has been changed
from (void *) to (union w_list_data *).

The formerly SIGBUSsing statement became quite elegant

        a->u = *data;

Given that it is a good bug catcher on Debian sparc, and more concise
than e.g.
        memcpy(&(a->u), data, sizeof(union w_list_data));
i tend to keep it.


To Sebastien:

Please give
   /home/thomas/xorriso-1.3.7/xorriso/xorriso
a thorough testing with your debian-cd setup.
("make dist" should even pack it up to a usable tarball)

Whatever the outcome will be with that strange strcmp() bug,
your original alternatives 1 and 2 have small chances to succeed
unless we declare surrender on 3.

1- It has been publicly stated in the past that Debian will not
   accept a package with original mkisofs. Stated reason was social
   incompatibility with its author.

2- Steve McIntyre prefers xorriso to take over genisoimage tasks
   rather than changing genisoimage code.
   From his view, xorriso is comfortably self-maintaining. :))
   I try to give him few reason to regret this strategy.

3- A xorriso candidate (rather stack sanitized than alignment
   corrected) has now been beamed onto your machine.


Have a nice day :)

Thomas
