Project: Qpid Dispatch

Affects Versions: 1.14.0

When the router receives two transfer frames back to back -
# First transfer frame is an empty with more=true
# Second transfer frame is also empty but with more=false
# Second transfer frame is also empty with more=false and abort=true
# Or - the client could send just one empty transfer frame with more=false,
abort=false
Under these conditions, the router crashes with the following backtrace -
