--rebuild-tree crashes

--rebuild-tree crashes

[Franz Mueller]

Hello reiserfs-Mailinglist,

the latest version of reiserfsck (3.6.13) doesn't help to solve my 
problem. I am using SuSE 9.0 with kernel 2.4.21. When I run

reiserfsck --rebuild-tree -S /dev/hdb4

I get the following error message:

Will rebuild the filesystem (/dev/hdb4) tree
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes if you 
do):Yes

Is there anything else that can be done?

Would you pack the fs metadata with 
    debugreiserfs -p -S /dev/hdb4 | bzip2 -c > hdb4.bz2
and allow us to download it? I would investigate the 
problem locally then.

Hello Franz,

the reiserfsprogs patch attached should cure for your problem.
Email me please about the result.
