[with patch] memory leak in gmp_globals.c

[mabshoff]

In gmp_globals.c we init tmp again instead of clearing it. This leaks about 16 bytes. For a patch see

​http://fsmath.mathematik.uni-dortmund.de/~mabshoff/patches/Sage-2.8.4.2-fix-small-mpq-leak-in-gmp_globals.c.patch

Without the patch:

==32229== LEAK SUMMARY:
==32229==    definitely lost: 2,548 bytes in 7 blocks.
==32229==      possibly lost: 364,814 bytes in 1,127 blocks.
==32229==    still reachable: 137,021,540 bytes in 18,327 blocks.
==32229==         suppressed: 0 bytes in 0 blocks.

With the patch:

==14532== LEAK SUMMARY:
==14532==    definitely lost: 2,532 bytes in 5 blocks.
==14532==      possibly lost: 364,878 bytes in 1,128 blocks.
==14532==    still reachable: 137,021,460 bytes in 18,324 blocks.

Every byte counts ;)
