(In reply to Ed Maste from comment #2)
We return SIGSEGV/SEGV_MAPERR, which is explained by POSIX as
'Address not mapped to object', which it is.

FreeBSD used to deliver SIGBUS in this situation, but it was rightfully
to SIGSEGV by davidxu AFAIR, and then I introduced compat sysctls to select
the specific signal to deliver.  See the story in PR 118304.
