Hm, this comes from vl.c:2989 (in git) calling g_mem_set_vtable(&mem_trace), which has been around since 2011 to add tracepoints for g_malloc/g_free.
https://github.com/GNOME/glib/blob/master/glib/gmem.c shows that this function is deprecated. This means that tracing won't work right, but should otherwise be innocuous. Will see what upstream thinks about it. ** Changed in: qemu-kvm (Ubuntu) Importance: Undecided => Low ** Summary changed: - glib/gmem.c: custom memory allocation vtable not supported + Memory tracing: glib/gmem.c: custom memory allocation vtable not supported -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1491972 Title: Memory tracing: glib/gmem.c: custom memory allocation vtable not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1491972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
