I've never seen that before!

What version of Linux are you running?

What version of Parted?  Did you compile it yourself?

What does mmap'ing to fd = -1 mean?  Prolly not relevant...

Those numbers look sane (the ones in the square brackets...).
I'm not sure what layout of _llseek() strace uses, but I'm assuming
what's in the square brackets is the offset...
