Description
Compiling and running this simplified version of src/examples/play.cpp (basically the same without a consumer):
#include <Mlt.h>
using namespace Mlt;
int main( int, char **argv )
{
Factory::init( NULL );
Profile profile;
Producer producer( profile, argv[ 1 ] );
return 0;
}
That code triggers a lot of leaks detected by valgrind:

Since a decent amount of them come from the factory construction, I tried to get the pointer to the Mlt::Repository that is returned by Factory::init(), and delete it before the end, but that triggers a Segfault instead. Am I missing something?

First steps
- Read the whole issue, then the project's contributing guide.

- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start with src/examples/play.cpp and the minimal program shown, running it under Valgrind to separate allocations from Factory::init and Producer construction. Trace the reported paths through mlt_factory_init and mlt_repository_init, then compare the leak report after any focused fix; done means the reproducible leaks are accounted for or eliminated.
