While researching the recent test run for clang in the freebsd ports,
one port I maintain ran into a bug, see:

http://pointyhat.freebsd.org/errorlogs/amd64-errorlogs/e.9-exp.20110723205754/cego-2.10.11.log

The author of cego and lfcxml investigated and built a testcase for the
problem,
which you can download from:

http://opsec.eu/src/clang-fbsd9-bug.tgz

Extract and run make on freebsd9-current displays:

$ make
clang++   -c Main.cc
clang++   -c Parent.cc
clang++   -c Child.cc
clang++   -c Master.cc
clang++ -v -o dtest Main.o Parent.o Child.o Master.o
FreeBSD clang version 3.0 (trunk 132879) 20110612
Target: x86_64-unknown-freebsd9.0
Thread model: posix
 "/usr/bin/ld" --eh-frame-hdr -dynamic-linker /libexec/ld-elf.so.1 -o dtest

clang++: error: linker command failed with exit code 1 (use -v to see
invocation)
