After adding some debugging into lookups/ldap.c, I came to the conclusion that the call to ldap_parse_url was not functioning correctly.
This reminded me that several years ago I had questions Sun as to why they were shipping ldap commands with the OS that did not support were not as current as the commands that came with their SunOne LDAP server, so I modified the local/Makefile to include the directory for the SunOne LDAP server include files and libraries, rather than relying on the default files that come with Solaris 10.

and then the ldapsearches work.

Shouldn't that be ldap://HOSTNAME:PORT/o=slb,c=blah...

You can see that at first something in his config had a servername
that appeared to be a valid hostname, but then after parsing the URL
to extract the host/port, it was not specified so it resulted in
nothing.
The bus error...isn't that due to free'ing a constant string?
...Todd
The configuration file defines ldap_default_servers:
ldap_default_servers = "\
gb0135ldap00.ldap.slb.com::390"
so the URL correctly substitutes this, and expands, but then after ldap_url_parse one sees the wrong host and port
LDAP parameters: user=NULL pass=NULL size=0 time=0 connect=0 dereference=0 referrals=on
perform_ldap_search: ldapm URL = "ldap:///o=slb,c=an?alias,mail,cn,ou,telephonenumber,o?sub?(&(mail=*)(alias=pkaturi))" server=gb0135ldap00.ldap.slb.com port=390 sizelimit=0 timelimit=0 tcplimit=0
after ldap_url_parse: host=o=slb,c=an port=954024
Hard coding the hostname into the LDAP URL, one gets a slightly different response (no bus error, but still an error in the LDAP URL parsing):

The Solaris version was compiled from source using Exim 4.80.1, while the Ubuntu package was installed as a package, and is based on 4.76. I do not see anything explicitly mentioned for LDAP lookups in the exim 4.80 change logs, but there has been changes to the lookups (new type dbmjz)
