This is a preprocess of libc++ <valarray>

Just noticed this.  preprocess enclosed.

$ clang++  -std=c++0x  valarray_crash.cpp 
clang: error: unable to execute command: Segmentation fault
clang: error: clang frontend command failed due to signal 1 (use -v to see

$ clang++ --version
Apple clang version 3.0 (trunk 131335) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin10.7.0
Thread model: posix

Sorry, it is a big enclosure, haven't nailed down what in there is causing the
crash.  Compiles normally without -std=c++0x.
