Using VIR_APPEND_ELEMENT here might look nicer, but that's just cosmetic. However this patch is incomplete - there's also a leak of volume_tokens mentioned in the bug that you didn't address: ==19011== 10 bytes in 1 blocks are definitely lost in loss record 14 of 82 ==19011== at 0x4A069EE: malloc (vg_replace_malloc.c:270) ==19011== by 0x38F0881041: strdup (in /lib64/libc-2.12.so) ==19011== by 0x40EB00: _vshStrdup (virsh.c:129) ==19011== by 0x40FC28: vshStringToArray (virsh.c:182) ==19011== by 0x414A66: cmdUndefine (virsh-domain.c:2609) ==19011== by 0x40D200: vshCommandRun (virsh.c:1652) ==19011== by 0x410964: main (virsh.c:3073) Maybe virStringSplit would give us an array that's easier to steal from?
