           Summary: Assertion failed: (TheCU && "Unable to find compile
                    unit!")
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal

         Component: Driver

I can't use clang to build llvm+clang because clang errors out in the configure
script with this error. I minimized the flags to the ones that error out. For
reference, the configure script executed this line:

0.    Program arguments: /usr/local/bin/clang -cc1 -triple
x86_64-unknown-freebsd9.0 -emit-obj -mrelax-all -disable-free -main-file-name
conftest.c -mrelocation-model static -mdisable-fp-elim -masm-verbose
-mconstructor-aliases -munwind-tables -target-cpu x86-64 -target-linker-version

The configure script was invoked as:
$ ../llvm/configure --enable-debug-runtime --enable-debug-symbols CFLAGS=-g
--with-llvmcc=clang CC=clang CXX=clang++
