{{Quickfixn}} Exception while processing the FIX messages

Mon Jul 13 10:17:59 PDT 2020

The fix is in, see https://github.com/connamara/quickfixn/pull/632

Raju, please give it a shot.  I think if you download and build the latest
source, your problem will go away.  (The version-specific dlls are in
Messages/FIX*).

Campbell, thanks for catching my diagnosis mistake.  I would have been mad
at myself later!
