Comment(by cypherpunks):

 Except memory corruption there are only one way to get this assert. Only
 if dump_microdescriptor() failed in some but wrote something to file, like
 annotation only or md->body partially. If that happens then every next
 md->off will point to some wrong place, and assert happen. We need to see
 actual log files, at least we should to see "After rebuilding microdesc
 cache, offsets seem wrong. " string there, even if theory wrong and code
 contains another way to trigger this assert.
