llvm-3.4 @3.4.2: Undefined symbols "llvm::LoopBase<llvm::BasicBlock, llvm::Loop>::~LoopBase()"

[ryandesign (Ryan Carsten Schmidt)]

Building llvm 3.4 fails on my Lion system with:

Undefined symbols for architecture x86_64:
  "llvm::LoopBase<llvm::BasicBlock, llvm::Loop>::~LoopBase()", referenced from:
      llvm::(anonymous namespace)::ScalarEvolutionsTest_SCEVMultiplyAddRecs_Test::TestBody() in ScalarEvolutionTest.o
ld: symbol(s) not found for architecture x86_64

System info:

$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.7.5
BuildVersion:   11G63

$ xcodebuild -version
Xcode 4.3.3
Build version 4E3002

$ clang -v
Apple clang version 3.1 (tags/Apple/clang-318.0.61) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

I realize newer Xcode and clang versions are available for Lion; mainly, this machine runs older versions in order to find problems.

Attached updated log for llvm-3.4 @3.4.2.

Building llvm-3.4 with clang-3.3 worked, so blacklisting Xcode 4.3's old clang would be one solution.
