Hi there,

Having implemented a custom perl module as a subordinate with back-perl, we've found a segfault when using slapcat to dump the database. The backtrace looks like this:

zeno:/home/build/rel-openldap# ./sbin/slapcat ./sbin/slapcat: Symbol `ldap_int_global_options' has different size in shared object, consider re-linking Here in new Posix Var 8192 and 4096 bdb_db_open: warning - no DB_CONFIG file found in directory /home/build/rel-openldap/var/openldap-data: (2).

*** glibc detected *** ./sbin/slapcat: free(): invalid pointer: 0x00000000009c5063 *** ======= Backtrace: ========= /lib/libc.so.6[0x7f1adc150948] /lib/libc.so.6(cfree+0x76)[0x7f1adc152a56] ./sbin/slapcat[0x42c11d] ./sbin/slapcat[0x42c1c9] ./sbin/slapcat[0x481448] ./sbin/slapcat[0x484c93] ./sbin/slapcat[0x4874b9] ./sbin/slapcat[0x408d40] /lib/libc.so.6(__libc_start_main+0xe6)[0x7f1adc0fb1a6] ./sbin/slapcat[0x4087d9]

Looks like an invalid pointer is being deferenced when running slapcat.

ATB,

Mark.
