Full_Name: hark Version: commit 9773f43b11aa8fac51407694bbdcd17830f206d5 OS: debian 9.0 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (195.169.146.71)

openldap is build with:

CFLAGS='-g' ./configure --enable-debug --enable-perl --enable-modules --enable-passwd LTCFLAGS='-g' export LTCFLAGS make depend make mkdir /root/openldapdebug/ make install STRIP='' DESTDIR='/root/openldapdebug'

started with:

gdb --args /root/openldapdebug/usr/local/libexec/slapd -d1 -h "ldap:/// ldapi:///var/run/slapd/ldapi" -F /etc/ldap/slapd.d

then when trying to do: ldapadd -x -w $PW -D cn=admin,cn=config -H ldap:"F2F -f /root/src/ldapcrash/slapd-add-perl.ldif

cat slapd-add-perl.ldif dn: olcDatabase=perl,cn=config objectClass: olcDatabaseConfig objectClass: olcDbPerlConfig olcDatabase: perl olcSuffix: dc=perl-example,dc=com olcPerlModulePath: /root/src/perlldap/ olcPerlModule: SampleLDAP olcPerlFilterSearchResults: FALSE #olcPerlModuleConfig: something

dn: dc=perl-example,dc=com objectClass: top objectClass: dcObject objectClass: organizationalUnit dc: perl-example ou: perl-example-ou

it crashes:
