Jeff Snider commented on COUCHDB-1177:
--------------------------------------
I have 1.1.1 pull replicating from 0.11.0 and it is failing with this bug. I
have -165 instead of -673327 but other than that it looks like the same thing.
Is this because I'm pulling from an old version or have I hit a regression?
Crash report below. Thanks.

> Project: CouchDB
> Issue Type: Bug
> Affects Versions: 1.0.1, 1.0.2

> LenLeft can still go negative. While the guard clause prevents an earlier
> bug, replication fails when it hits this issue.
> In the following case, LenLeft is -673327 which matches no clauses (we expect
> either 0 or > 0). Somehow we are starting with a LenLeft value lower than the
> number of bytes we subsequently receive.
