Agreed.

Only libasan is currently broken. With attached patch, I've
confirmed libasan successfully builds, and system boots
multiuser on TME.

I've never tested asan on sun2, as it does not work anyway.
Also, affects of this patch for other m68k ports are not
even compile-tested...

For sun2, GCC cannot build natively for years. It may be
better just to disable asan for m68000.

Thanks,
rin
