Are you sure the memory is leaked? I suspect malloc simply doesn't
return the pages to the OS (no sbrk() call to shrink the heap) or you
have a minor case of memory fragmentation (totally normal).  This is
almost certainly the case if you are using 'top' to view memory
consumption: a process's heap does not shrink from the peak consumption
if you just have a minor reduction in heap size and/or have some

To really analyze leaks, you should use valgrind.  If valgrind does not
show a problem, your issue is not a memory leak.

Happy hacking!
