Sadly, I can confirm: weston swelling to double size on qemuarm64 is caused
by this recent change in glibc:
+EXTRA_OECONF_append_aarch64 = " --enable-memory-tagging"
You can verify with this innocent looking program. Run 'free' while it is
running and compare with and without tagging:
main()
{
for (int i=0; i<768; i++)
calloc(1,262368);
sleep(200);
}
I'll queue a revert.
