Doesn't work (Sun/SPARC Solaris 2.6 with egcs 1.0.3):

CFLAGS="-s -O3 -D_REENTRANT" ./configure --enable-shared --enable-cldap --with-ldbm-api=db2 --with-threads=posix

Hhmh, the machine has 768 MByte physical memory and 1.2 GByte of
swap. My slapd.conf values are:

cachesize       100000
dbcachesize     15000000
dbcachenowsync
sizelimit       1000000

Are this really too high values?
