The netbsd-4 compat_defs.h doesn't prototype user_from_uid()
(or even the transformed __nbcompat_user_from_uid()) at least
with a netbsd -current build host. With a -current amd64 build
host, the address returned by user_from_uid() is > 4GB, so get
truncated and sign extended to an invalid address. The prototype
for user_from_uid() in <pwd.h> isn't visible either because
_NETBSD_SOURCE isn't defined.
I guessing that the return addresses from malloc() might have
changed with the switch to jemalloc, and this is why it hasn't
been an issue in the past?
Check out a netbsd-4 source tree on amd64 -current host, try to
Not sure. Pull in -current user_from_uid()/group_from_gid()
compat_defs.h logic ?
A workaround is to just comment out the HAVE_USER_FROM_UID and
HAVE_GROUP_FROM_GID checks in compat_defs.h so that the prototypes
for those functions are always visible.
Build host userland is -current from March 30 2008
Target sources are netbsd-4 from April 14 2008
