Sorry!

mdadm version 2.6.6 although it is reported as:
monosan:~ # mdadm -V
mdadm - v2.6 - 21 December 2006
I accidentally compiled mdadm 2.6 instead of 2.6.6. But this is even
worse:

monosan:~ # mdadm -V
mdadm - v2.6.6 - 19th May 2008
monosan:~ # mdadm -As
Segmentation fault

That's bad.
What do you get from:

 ulimit -c unlimited
 mdadm -As
 gdb `which mdadm` core
 where

I saw this last week, but can unfortunately only offer limited information - for various reasons, this system is no longer available.

On an up to date Fedora 8 x86_64 2.6.24.7-92.fc8 sytem, I replaced mdadm with a locally built mdadm 2.6.5 - compiled with -O2.

On the next reboot, the md RAID1 / failed to assemble, with mdadm errors. When I accessed from a rescue disk, running mdadm -A /dev/mdX (can't rember exact dev), returned "Segmentation fault".

If it's any use, I do still have a complete mdadm 2.6.5 tree containing the faulty objects from this system.

Richard
