Memory leak

[James Devine]

I've noticed if I set a hint such as

DEFAULT
        NAS-IP-Address := "%{Packet-Src-IP-Address}"

I end up with a memory leak that valgrind shows as:


==14825== 429,936 bytes in 1,378 blocks are definitely lost in loss
record 332 of 332
==14825==    at 0x4C284A8: malloc (vg_replace_malloc.c:236)

I tested this on freeradius 2.1.9
