            if self.blocksize - self.blk_off < HEADER_SIZE {

would you mind trying out what happens if you change this to self.blocksize < HEADER_SIZE + self.blk_off? This would avoid an overflow but should (mathematically) be equivalent.

There is a bug when recovering the manifest, in version_set.rs line ~693. The descriptor_log should be opened using new_with_off to recover the offset.

This is a great find, would you mind sending a PR? (so the credit is yours)
