Ah, thanks for the reference.  It sounds like GCC should call mpfr_free_cache
before exiting as is recommended in section 4.7 Memory Handling of the MPFR
manual (as I just discovered by searching for the function):

It is strongly advised to do that before terminating a thread, or before
exiting when using tools like ‘valgrind’ (to avoid memory leaks being
reported).

The only mpfr_free_cache call I see in GCC is in the Fortran front end.  
Without such a call on exit, leaks in MPFR need not be meaningful.
