I though I suffered from pkg/53348 or pkg/53671 on NetBSD 8.0. I though 
that backport the fix of kern/52598 should fix them. I need this host 
since it build sets of custom packages for several domU running 8.0. 
Otherwise, I would have updated it to 9.0_RC1.

Unfortunately, the system just crashes during a bulk build (when 
building lang/spidermonkey52) with the following backtrace:
# crash -M netbsd.10.core
Crash version 8.0, image version sys/arch/amd64/c.
WARNING: versions differ, you may not be able to examine this image.
System panicked: trap
Backtrace from time of crash is available.
