So far the only fix that we have had posted on the list is https://lists.gnu.org/archive/html/qemu-devel/2022-10/msg00391.html by Daniel. The approach that I'm following here should have the same outcome, except that it doesn't change the guest's environment. The approach is to import GTree (sans GSlice) into QEMU, and use that for TCG. Daniel: what is the testing that you're using? Could you test these patches to confirm they fix the issue? Regarding performance, it looks like GSlice does buy us something, which might explain why GLib's maintainers don't want to change it. But I'd put correctness over performance any day. Furthermore, we could use an alternative tree implementation; I've tried CCAN's AVL and the performance impact is lower (I believe due to faster traversals), although I'm going with a straight import of GTree here to keep the API identical (and also avoid any potential correctness concerns). Thanks, Emilio
