Segfaults on FreeBSD

Hi, 
I keep getting segfaults within cryptopp on freebsd for at least PBKDF 
DeriveKey(). I used the sample code from the wiki:  
https://www.cryptopp.com/wiki/PKCS12_PBKDF

I used the cryptopp-lib that is available through the binary ports 
collection (pkg). The reported version is 8.5.0

Any ideas on how I can fix this or at least where to look?

Below all the technical info about versions and traces for a first triage.
