mdadm 3.2.5: SEGFAULTS caused by sha1-includes.diff patch!

[Sebastian Riemer]

Hi there,

we've backported mdadm 3.2.5 to Debian Squeeze by reverting the
following commit:
d98f009: move initscript metadata from /lib/init/rw/.mdadm to /run/mdadm

We've encountered segfaults with activated bitmap and we could trace the
issue to the "sha1-includes.diff" patch.

Test with sha1-includes.diff:
# dd if=/dev/zero of=/dev/loop0 bs=1M count=20
# dd if=/dev/zero of=/dev/loop1 bs=1M count=20
# mdadm -C /dev/md0 -e 1.2 -b internal -l 1 -n 2 /dev/loop0 /dev/loop1
# mdadm -S /dev/md0
# mdadm --zero-superblock /dev/loop0
Segmentation Fault

The segfault is triggered always for sure if bitmap data is activated on
the volumes.

Test without sha1-includes.diff and "binutils-dev" added to build depends:
Same test commands but works as expected.

Please check and correct this!

Cheers,
Sebastian
