Re: [Quickfix-developers] Memory Leaks Version 1.5

[Oren M. <ore...@ya...>]

This is probably more to do with tradeclient than with
QuickFIX itself.  The tradeclient is aborted using
ctrl-c which is forcing the application to exit
without cleaning up the stack.  I would guess these
are the memory leaks you are seeing.  If you modify
tradeclient so that you it will terminate gracefully,
you should see better results.

There are only two places where memory leaks had been
discovered.  These were with repeating groups, which
is the only class in the QF C++ library that does any
heap allocation, and in the JNI wrapper which needs to
do heap allocation + allocate JVM resources.
