Problem with searched on boolean values

[Joseph Annino <jannino@jannino.com>]

I have an LDAP directory with custom schema that specifies several fields
whose values can be 0 or 1, a boolean.  When I try and do a search for
specific value of one of these parameters openldap always crashes.  If I do
a search on just entries that include that parameter, everything is fine.

I have tried different indexing settings and reindexing the data files.  I
couldn't find any problems like this in the archives.  I can provide some
more information for helping to track this down if needed.

The definition of the specific parameter I am having problems with is:

attributetype ( 1.3.6.1.4.1.8681.1.41 NAME 'freespeechActive'
        EQUALITY numericStringMatch
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.36{1} SINGLE-VALUE)

In slapd.conf I have setup an equality index on this.  It crashes with or
without the index.
