As you can see, I am using the default Apple linker, and hardened settings = for the compiler. Try using those settings yourself, and see what comes out= .

I can replicate your log when using the default tool-chain by Apple. The following causes my system to fail with openldap, replicating my original bug. The same settings succeed with many other open source projects: openldap is the only one that fails.

Then it sounds like OpenLDAP is tripping a bug in LLVM or related tools. Again, there are no duplicate symbols in the liblber library.
