None of the above. It first failed from a Debian installation, 
then I rebuilt it from scratch and got the same error. It 
doesn't fail checking any of my other partitions, just this 
one, and it dies in the same spot each time.

ok, would you run 
	debugreiserfs -p /dev/xxx | bzip2 -c > xxx.bz2
and privide it for downloading, I will test it locally on your data.

yes, it was a bug. The patch attached will solve the problem.

rebuild-tree fails in pass 2

[Michael Harnois]

I am running a 2.6.1 kernel pulled from bk yesterday and using 
reiserfsprogs-3.6.11. Something happened after I rebooted that 
caused filesystem corruption which instructed me to run 
rebuild-tree. But it will not run to completion. During pass 2 
it fails with 
	Assertion `*first < bm->bm_bit_size' failed 
 
Any ideas?

Looks like a broken hardware (RAM?) or probably you build the 
progs not statically on one computer and then run reiserfsck on 
another one (with another glibc installed). Would you check it?
