Hey, We've solved this by using a smart memory profiling tool, which knows if memory should or should not be freed and this tool is valgrind. THe magic command line I'm using is: G_SLICE=always-malloc GST_REGISTRY_FORK=no valgrind --leak-check=full --leak-resolution=high player/.libs/lt-swfplay test.swf That will give you quite a bit of output on stderr, so it might be useful to redirect it to a file. Only stuff which is marked as "definitely lost" is memleak, "possibly lost" often is not (but might be).
For added fun you can add --show-reachable=yes to get all the in-use memory listed, too.
