In this case it's a qemuMonitorEventPanicInfoPtr. Signed-off-by: John Ferlan --- Noticed this while working through the DumpComplete patch series. One has to follow the bouncing ball, but will note that when the processEvent->data is passed to other cases, it ends up getting VIR_FREE()'d at the end of various functions, so this should too since it's at the end of the line. src/qemu/qemu_driver.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a203c9297..5eaf97a46 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -4309,6 +4309,7 @@ processGuestPanicEvent(virQEMUDriverPtr driver, qemuDomainRemoveInactiveJob(driver, vm); =20 cleanup: + qemuMonitorEventPanicInfoFree(info); virObjectUnref(cfg); } =20 --=20 2.13.6 -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
