Also the usage virCommand with respect to buffer is very odd. ==2504== 1,100 bytes in 1 blocks are definitely lost in loss record 167 of 175 ==2504== at 0x4C2CE3F: malloc (vg_replace_malloc.c:298) ==2504== by 0x4C2F1BF: realloc (vg_replace_malloc.c:785) ==2504== by 0x5D32EE2: virReallocN (viralloc.c:245) ==2504== by 0x5D37278: virBufferGrow (virbuffer.c:150) ==2504== by 0x5D3783E: virBufferVasprintf (virbuffer.c:408) ==2504== by 0x5D377A9: virBufferAsprintf (virbuffer.c:381) ==2504== by 0x57017C1: qemuBuildSevCommandLine (qemu_command.c:9707) ==2504== by 0x57030F7: qemuBuildCommandLine (qemu_command.c:10324) ==2504== by 0x575FA48: qemuProcessCreatePretendCmd (qemu_process.c:6644) ==2504== by 0x11351A: testCompareXMLToArgv (qemuxml2argvtest.c:564) ==2504== by 0x1392F7: virTestRun (testutils.c:180) ==2504== by 0x137895: mymain (qemuxml2argvtest.c:2900) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- src/qemu/qemu_command.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-)
