I've tried mounting this (copy of the live) disk on a RHEL5 system, and 
fsck-ing it there (ocfs2-tools-1.4.1-1.el5): exactly the same thing 
happens.  Running with -v, the last few messages are

update_inode_alloc:157 | updated inode 1266864 alloc to 1 from 1 in slot 0
o2fsck_verify_inode_fields:435 | checking inode 1266865's fields
check_el:249 | depth 0 count 243 next_free 1
check_er:164 | cpos 0 clusters 1 blkno 26127524
verify_block:705 | adding dir block 26127524
update_inode_alloc:157 | updated inode 1266865 alloc to 1 from 1 in slot 0
o2fsck_verify_inode_fields:435 | checking inode 1266866's fields

check_er:164 | cpos 0 clusters 1 blkno 75809517
o2fsck_mark_cluster_allocated: Internal logic faliure !! duplicate 
cluster 75809517
verify_block:705 | adding dir block 75809517

and then it hangs.

btw,

someone needs to set an svn:keywords property :)
