This sounds eerily similar to port-macppc/54827 - there's quite a bit of confusion early on on my part there, but scroll to the last couple of mails. http://gnats.netbsd.org/54827 It looks like some logic changed in MI gcc8 that broke netbsd MD config headers and I wonder if you see the same problem here. For macppc the fix was also to undo the netbsd change to STACK_BOUNDARY in favor of PREFERRED_STACK_BOUNDARY. May be we should also check other ports for similar gotcha proactively? -uwe
