ofs seems to be broken:
(gdb) print *(ofs)
$6 = {
fs_devname = 0xffffffffffffffff <error: Cannot access memory at address
0xffffffffffffffff>,
fs_flags = 4294967295,
fs_io = 0xffffffffffffffff,
fs_super = 0xffffffffffffffff,
fs_orig_super = 0xffffffffffffffff,
fs_blocksize = 4294967295,
fs_clustersize = 4294967295,
fs_clusters = 4294967295,
fs_blocks = 18446744073709551615,
fs_umask = 4294967295,
fs_root_blkno = 18446744073709551615,
fs_sysdir_blkno = 18446744073709551615,
fs_first_cg_blkno = 18446744073709551615,
uuid_str = '\377' <repeats 33 times>,
fs_cluster_alloc = 0xffffffffffffffff,

fs_system_inode_alloc = 0xffffffffffffffff,
fs_eb_allocs = 0xffffffffffffffff,
fs_system_eb_alloc = 0xffffffffffffffff,
fs_dlm_ctxt = 0xffffffffffffffff,
ost = 0x10002aa0005d040,
qinfo = {{
qi_inode = 0x0,
flags = 0,
qi_info = {
dqi_bgrace = 0,
dqi_igrace = 0,
dqi_syncms = 0,
dqi_blocks = 0,
dqi_free_blk = 0,
dqi_free_entry = 0

}, {
qi_inode = 0x0,
flags = 0,
qi_info = {
dqi_bgrace = 0,
dqi_igrace = 0,
dqi_syncms = 0,
dqi_blocks = 0,
dqi_free_blk = 0,

}
}},
fs_private = 0x0
}
and its pointer is passed along the stack trace since frame #1
(scan_raw_disk).
It comes from:
* ocfs2_open is modified to be aware of OCFS2_FLAG_IMAGE_FILE.
* open routine allocates ocfs2_image_state and loads the bitmap if
* OCFS2_FLAG_IMAGE_FILE flag is passed in
ret =
ocfs2_open(src_file,OCFS2_FLAG_RO|OCFS2_FLAG_NO_ECC_CHECKS|open_flags,
0,0, &ofs);
And likely related to how bitmap is disposed in the image file for a big
endian arch.
ofs->ost pointer is not broken, because it comes from a malloc call
after ofs was "allegedly" correctly read (which is not true in big
endian arches):
ret = ocfs2_malloc0(sizeof(struct ocfs2_image_state),&ofs->ost);
