Segfault with Libcrypto.so

[Nicola Tuveri]

Is it possible you have compiled and installed the openldap tool you are
using against an older version of the system installed openssl library
which has since been updated?

In that case you would probably need to recompile and reinstall your custom
openldap against the new version of the library.

Best regards,

Nicola Tuveri
