Hello! I built Debian glibc 2.5-4 on GNU/Hurd using GCC 4.1 instead of 4.0, having applied a few patches I crafted already some time ago. It basically works. :-)
However, if I try to log in on the console (`ssh'ing in works just fine)
it fails with ``login: Authentication failure: (ipc/mig) server died'',
and that's due to a `EXC_BAD_ACCESS' in the spawned `/hurd/password'
process.
#v+
$ sudo gdb /hurd/password 328
[...]
Program received signal EXC_BAD_ACCESS, Could not access memory.

Do the glibc people have an offhand idea what might be going on in the
nss code?
