Are you famiiar with valgrind? It is a great tool for detecting memory
leaks. I used it to oonfirm that GMP indeed does not leak for your test
cases. (You seem to have forgotten to mention the system you used for
these experiments; I used an amd64 cpu running debian.)
Your analysis of what is a memory leak is incorrect. You might need to
better understand the role of malloc/free (in the C library) and the
underlying system memory handling functions (sbrk/brk/mmap/munmap). The
former do not necessarily give back its memory to the system. That's
not a memory leak by normal definitions. Or at least, an application
cannot affect this "leak".
Again: No GMP bug.
The GMP lists are not the right place for discussions about how malloc
interfaces to the kernel. But I am sure there are great explanations
which you will be able to find on the Net.
