First, if you're wanting the code in DebugInstrumentation.cpp, you need 
to get the version in my patch 
(http://llvm.cs.uiuc.edu/~criswell/sc.tar.gz).  The debug metadata API 
changed between LLVM 2.6 and LLVM 2.7, so if you're working with 
mainline LLVM, you should get the newer version of the code that is 
available in the patch.

Second, to answer your specific question, I believe you have a 
mismatched version of llvm-gcc or Clang.  Please see my answer on svadev 
this morning to the same issue: 
http://lists.cs.uiuc.edu/pipermail/svadev/2011-July/000086.html; this 
will hopefully fix your problem if, in fact, you do want to compile 
SAFECode.
