Can you check, whether dmd is explicitly linking with -pthread?
It might an issue of libkse vs. libthr?
https://github.com/freebsd/freebsd/blob/0680c1f5fe159bba69a242568af0db7d7dc15a79/lib/libthr/thread/thr_clean.c#L49
We're building the binary releases on FreeBSD 8.4, so upgrading might 
help too.
