I am developping a multithreaded application which seems to allocate huge amounts of memory during its runtiime. All the memory gets freed in the end of execution, so valgrind shows no memory leaks. I tried to use massif tool to find out what was happening, but ms_print seems to show information only about the main thread. However, I believe that the great majority of memory is allocated in child threads. Is it possible to make massif show information about them?
Does massif tool work correctly with multithreaded applications?

For me (Ubuntu 12.04), this seems to work by default. Like in your application, my main thread doesn't do much of anything (except handling my gtk-based UI), and all the (de)allocating is done in subthreads.
I did have some initial difficulty because I am analysing an autotools-based project, and in my first attempts I was analyzing a shell-script generated by libtool, instead of my application.
