RE: [Quickfix-users] user defined types seems to break typesafe cracking in C++

[Murphy, R. <Ric...@ci...>]

Oren,

I've attached a file. The first line is the fix msg with the legsymbol
the second is the msg without the legsymbol  (id=3D600).

Fyi my current workaround is to comment out the checksym check in
Message.cpp and rebuild quickfix.=20

Thanks,
Richard.=20

Richard,

Can you post your actual messages (with and without the LegSymbol)?
