That will be a linkage problem. The name service switch will be
dynamically loading a db driver in the form of a shared object,
which is probably also pulling in a db library that clashes with
the one that Exim is linked with. I suggest playing around with
ldd, exim, and /lib/libnss_*.
In fact, on this Debian box, I find that
:; ldd /usr/sbin/exim
libident.so.0 => /usr/lib/libident.so.0 (0x4001d000)
libpcre.so.3 => /usr/lib/libpcre.so.3 (0x40020000)
libnsl.so.1 => /lib/libnsl.so.1 (0x4002a000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x4003e000)
libpam.so.0 => /lib/libpam.so.0 (0x4006b000)
libdb2.so.2 => /lib/libdb2.so.2 (0x40073000)
libresolv.so.2 => /lib/libresolv.so.2 (0x400b4000)
libldap.so.2 => /usr/lib/libldap.so.2 (0x400c4000)
liblber.so.2 => /usr/lib/liblber.so.2 (0x400e9000)
libc.so.6 => /lib/libc.so.6 (0x400f3000)
libdl.so.2 => /lib/libdl.so.2 (0x40211000)
libsasl.so.7 => /usr/lib/libsasl.so.7 (0x40214000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
:; ldd /lib/libnss_db.so.2
libnss_files.so.2 => /lib/libnss_files.so.2 (0x4000e000)
libdb3.so.3 => /usr/lib/libdb3.so.3 (0x40017000)
libc.so.6 => /lib/libc.so.6 (0x400c0000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
Note that they require different versions of libdb, which is
what might be causing the crash. I suggest reporting this to
Debian as a bug.
