clang: error: unable to execute command: Illegal instruction: 4
clang: error: clang frontend command failed due to signal (use -v to see
invocation)
clang: note: diagnostic msg: Please submit a bug report to
http://llvm.org/bugs/ and include command line arguments and all diagnostic
information.
clang: note: diagnostic msg: Error generating preprocessed source(s) - no
preprocessable inputs.
djc at djc-mbp lang $ clang -v
clang version 3.1 (branches/release_31)
Target: x86_64-apple-darwin12.2.0
Thread model: posix

No need to add a stacktrace after the error message. (Also, the LangRef fails
to clarify the need for constant arguments.)
