Hi Vladimir,
My setup : 4x 12 disks x72Go RAID 5 on a RAID PERC3/QC
Partition size is about 1.7 To
mkreiserfs segfaults when i try to make the partition. I can reproduce it
every time.
Here is the gdb trace:
(gdb) set args --hash r5 --format 3.6 /dev/sdd1

The fact is that it dosn't happen with 3.x.0j:

I re-did the test with a 500Go volume and this time mkreiserfs
3.x.0k-pre13 didn't segfault.
This is a test server so i can test all software/kernel versions you would
like to see me run.
Thanks,
Philippe.
