Yes, please do.  I can reproduce this using e2fsprogs 1.43's next
branch, so there is definitely a real bug in e2fsprogs's resize2fs.

The fastest way to reproduce this is using tmpfs (it only requires
275MB of ram):

#!/bin/bash
FS=/tmp/foo.img
touch $FS
mkfs.ext4 $FS -i 262144 -m 0 -O 64bit 15627548672k
resize2fs -p $FS 19534435840k
resize2fs -p $FS 23441323008k
debugfs -c $FS -R "stat <2>"

Cheers,

						- Ted
