ext2fs_check_desc: Corrupt group descriptor: bad block for block bitmap
The filesystem size (according to the superblock) is 48 blocks
The physical size of the device is 37 blocks
Either the superblock or the partition table is likely to be corrupt!

The culprit appears to be this line in show_stats():
frag_percent_total = ((10000 * (ctx->fs_fragmented +
ctx->fs_fragmented_dir))
/ inodes_used);
This doesn't quite work if inodes_used is 0.
