Re: [Boost-users] [boost.lambda] memory leak with bind/shared_ptr combination?

Hello,

I'm using gcc 3.2.3, Boost 1.33.1 on RedHat Linux 3.4.6. I can clearly
see the process memory usage increase as the program runs (using tools
like ps/pmap/top etc). Any ideas or tips to help me figure out what's
going on? 

-Thanks!
