Re: cmake core dumps in -6 emulation

That, way, it proceeds past the error.
I can then interrupt it and proceed with a normal make build.
That core dumps again (later); ktrace-d, it proceeds past the error again.
Interrupt, proceed normal. core dumps.
Finally, I get a core dump with the ktrace-d run, but no sensible backtrace.

Last entries of the process dumping core:

So could this be a problem with libkver?
