found it!

that is "defghijklmnopqrstuv..." instead of the expected "1234567890abc..."

13 bytes!

b->data is incremented (and b->len decremented)13 bytes to skip the
"venti config" magic in readifile() ifile.c:39.
and freezblock() alculates the position of the zmagic by b->data + b->_size.

maybe add a b->_data in ZBuffer or fix ifile.c?
