This is weird, I can't reproduce the bug with the patch...

Are you sure they really are memory errors ? Valgrind uses to report lots
of ioctl errors that indeed are not really errors when I use it to debug 
Parted :p

I agree that would make more sens.

I reproduced your partition scheme, with a supplementary partition 10
from 41 to 49g, formatted everybody with ext3, deleted it and rescued it
without any problem, but well this test doesn't mean anything because
it could be different from the exact position of your partition 10
