We discovered a few days ago that LTO broke qemu on aarch64. The original bug reported was: https://bugzilla.redhat.com/show_bug.cgi?id=1893892 But actually looking at the build.log[1] we see another assertion failure in the test suite. (Unfortunately although we run the test suite, the spec file was ignoring the result so the broken build escaped into Rawhide.) Because qemu is a complicated piece of software we're not clear if the bugs found are general bugs in LTO, bugs which are specific to LTO on aarch64, or bugs in qemu which are exposed by optimizations made possible by LTO. One thing we do suspect is that this could be the tip of the iceberg since the qemu test suite only tests a tiny fraction of the code. LTO has been disabled across all arches for now.
