The backtrace shows that these SSL functions are contained inside your 
libldap_r shared library object file. Usually they should be present in 
OpenSSL's own shared libraries. If OpenSSL was only provided as a static 
library, it's not clear that their code will behave correctly when used inside 
a shared library (i.e., PIC vs non-PIC dependencies).

It would also help if you compile without optimization, with debug symbols, 
and run the non-stripped binaries. Your backtraces are lacking a lot of info 
at the moment.
