Hi,
sorry for mis-posting the first reply for bug 746254 to this bug 731806.
Meanwhile it turned out that the SIGBUS vanishes if i do not
compile with -O2 or if i replace "a->u =" by memcpy().
So it seems worth to check whether genisoimage resp. strcmp() work
properly if not compiled with -O2.
--------------------------------------------------------------------
A test with Sebastiens genisoimage options succeeded without error.
/home/thomas/xorriso-1.3.7/xorriso/xorriso -as mkisofs \
-r -J -o test.iso -G ~/boot/isofs.b -B ... tmp-iso/miniiso/cd_tree
It looks ok, SPARC-boot-wise.
SUN SPARC disklabel: CD-ROM Disc with Sun sparc boot created by libisofs
SUN SPARC secs/head: 640
SUN SPARC heads/cyl: 1
SUN SPARC partmap : N IdTag Perms StartCyl NumBlocks
SUN SPARC partition: 1 0x0004 0x0010 0 16940
SUN SPARC partition: 2 0x0002 0x0010 0 16940
...
SUN SPARC partition: 8 0x0002 0x0010 0 16940
An additional option --md5 enabled confirmation that the ISO stream
of libisofs was written flawlessly by libburn into the file test.iso.
/home/thomas/xorriso-1.3.7/xorriso/xorriso \
-for_backup -indev test.iso -check_media --
xorriso is willing to load the ISO metadata and to compare it with
the hard disk tree.
/home/thomas/xorriso-1.3.7/xorriso/xorriso \
-indev test.iso -compare_r tmp-iso/miniiso/cd_tree /
It only detects the consequences of option -r with directories
(see man genisoimage / mkisofs):
Permissions are set to "r-xr-xr-x", owned by 0, group is 0.

Have a nice day :)
