Bug#40768: nscd causing SIGBUS on debain-sparc

[Mike <mike@vee.net>]

Package: nscd
Version: 2.1.1-9

Nscd appears to be causing programs to fail with a SIGBUS when resolving
hostnames. I have noted this behaviour in both apt-0.3.6 and
sendmail-8.9.3-1. Stopping nscd or disabling the nscd hostname cache
fixes the problem, i.e. the programs no longer SIGBUS.

The problem was discussed briefly on the debian-sparc list under the
subject "apt ftp method dying after upgrade".

The following is a stack trace from apt-get's ftp method:

read(3, "search vee.net\nnameserver"..., 4096) = 90
read(3, "", 4096)                       = 0
close(3)                                = 0

read(3, "\0\0\0\0\0\0\0\1\0\0\0\25\0\0\0\1"..., 32) = 32
readv(3, [{"mirror.aarnet.edu.au\0", 21}, {"\0\0\0\22", 4}, {"\300o \2",
4}, {"\
0\0\0\0\0\0\0\0\0\0\377\377\300"..., 16}], 4) = 45
read(3, "ftp.au.debian.org\0", 18)      = 18
close(3)
--- SIGBUS (Bus error) ---

The machine is a SparcStation 5, running Debian 2.1, Linux 2.2.10,
libc6-2.1.1-9.
