RE: OpenLDAP 2.1.8 on Win2000

["Howard Chu" <hyc@highlandsun.com>]

Looks like you've run out of stack space on that particular thread. The next
function, after bdb_dn2idl, is probably bdb_idl_fetch_key() which requires
1.3MB of stack all by itself. Since you're running BDB 4.1.24 it would be
safe for you to reduce this requirement by patching (in back-bdb/idl.c
bdb_idl_fetch_key()) the declaration
	ID buf[BDB_IDL_DB_SIZE*5];
to just
	ID buf[BDB_IDL_DB_SIZE];

Generally when back-bdb is used you need at least 2MB of stack space per
thread. It looks like libldap_r's thr_nt.c doesn't explicitly set the thread
stack size, so that's part of the problem as well. I have no idea how big the
default size is, it depends on your compiler/linker and you can override it
at link time.
