Re: [Quickfix-developers] Upgrading to quickfix 1.12.4: C++/MySQLConnection.h:98: warning: suggest parentheses around assignment used, as truth value

I would not recommend 1.12.3 over 1.12.4. We just haven't yet added =20
a tag for 1.12.4. What exists in the repository is newer than both =20
those versions. The warning isn't that troubling, what I'm wondering =20=
is if their is still a crash with the latest from svn. Is there?
If so can you put together a sample application and config that we =20
could use to replicate it? I put together a basic acceptor that uses =20=
the MySQLStore and was not able to duplicate the crash with the svn =20
version.
