Building unix software with debugging symbols is basic system administrator 
knowledge.  There is nothing "openldap" specific about doing so.  Same with 
debugging the core files that are generated.

Here's a page on basic C compilation:

<http://www.cs.rutgers.edu/LCSR-Computing/programming.html>

Most specifically, note the "-g" option to CFLAGS, which instructs gcc, in 
this case, to include debugging symbols in the resulting compiled code.

Ensure that when you install, you set STRIP="" so that the "make" program 
does not strip out the debugging symbols on installation.  Run the new 
slapd that has the debugging information and get a core file.  Use GDB to 
get a backtrace from it.

Again, nothing here is specific to OpenLDAP, which is why there is no 
"OpenLDAP" page on how to do this.  I will note the FAQ is fully 
interactive, allowing anyone to create an entry, if you feel so inclined. 
I would suggest updating <http://www.openldap.org/faq/data/cache/59.html> 
with any information you feel specifically is lacking.
