function_clause error in write_streamed_attachment
--------------------------------------------------
Key: COUCHDB-1177
URL: https://issues.apache.org/jira/browse/COUCHDB-1177
Project: CouchDB
Issue Type: Bug
Reporter: Robert Newson
Fix For: 1.0.2, 1.0.1
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.
