OK, after installing gdb-4.18 (very surprised it wasn't there)
I had a look at the core dump, and my intuition (that it had to
do with regular expressions) proved to be right:

Core was generated by `../servers/slapd/slapd -f ./data/slapd-master.conf -p 9009 -d 5'.

Now on Solaris 2.6 we have this:

C Library Functions                                   regcomp(3C)
 
NAME
     regcomp, regexec, regerror,  regfree  -  regular  expression
     matching
 
SYNOPSIS
     #include <sys/types.h>
     #include <regex.h>
 
     int regcomp(regex_t *preg, const char *pattern, int cflags);
 
     int regexec(const regex_t *preg, const char *string,
          size_t nmatch, regmatch_t pmatch[], int eflags);
 
     size_t regerror(int errcode, const regex_t *preg,
          char *errbuf, size_t errbuf_size);
 
     void regfree(regex_t *preg);


and on Solaris 2.4:

regcmp(3G)             C Library Functions             regcmp(3G)
 
 
 
NAME
     regcmp, regex - compile and execute regular expression
 
SYNOPSIS
     cc [ flag ... ] file ...  -lgen [ library ... ]
 
     #include <libgen.h>
 
     char *regcmp(const char *string1, /* char *string2 */ ... ,
          int /*(char *)0*/);
 
     char *regex(const char *re, const char *subject,
          /* char *ret0 */ ... );
 
     extern char *__loc1;
 
MT-LEVEL
     MT-Safe
 
DESCRIPTION
     regcmp()  compiles  a  regular expression (consisting of the
     concatenated arguments) and returns a pointer  to  the  com-
     piled form.  malloc(3C) is used to create space for the com-
     piled  form.   It  is  the  user's  responsibility  to  free
     unneeded  space  so  allocated.  A NULL return from regcmp()
     indicates an incorrect argument.  regcmp(1) has been written
     to generally preclude the need for this routine at execution
     time.



Maybe I should use a different regex package, as suggested in

http://www.openldap.org/its/index.cgi/Incoming?id=136;expression=regex;user=guest;statetype=-1

GNU regex 0.12 OK?

Are there provisions in OpenLDAP to use that instead of the
system version?


Cheers,
