[libvirt] [PATCH] python: plug memory leak on libvirt_virConnectOpenAuth
From: Alex Jia <ajia(a)redhat.com>
* Detected by valgrind. Leak introduced in commit 5ab109f.
* python/libvirt-override.c: avoid memory leak on libvirt_virConnectOpenAuth.
* How to reproduce?
% valgrind -v --leak-check=full virt-clone --print-xml
Note: it can hit the issue although options are incomplete.
* Actual valgrind result:
==1801== 12 bytes in 1 blocks are definitely lost in loss record 25 of 3,270
==1801== at 0x4A05FDE: malloc (vg_replace_malloc.c:236)
