Thanks for mentioning it, but I think of this as a pseudo leak,
since that allocated storage is still reachable at exit:
$ valgrind --leak-check=full --show-reachable=yes ./id -G
...
==18858== 9 bytes in 1 blocks are still reachable in loss record 1 of 4
==18858== at 0x4C20FAB: malloc (vg_replace_malloc.c:207)
==18858== by 0x403D49: xstrdup (in /f/w/cu/src/id)
==18858== by 0x40198E: main (id.c:214)
...
IMHO, it's best not even to try to free such memory,
unless the total amount can become large enough to interfere
with regular operation.
