[LLVMdev] between r241513 and r241594, clang 3.7.0svn now crashes building clang-tools-extra
Since we are only a week away from branching for 3.7.0, this new breakage in the stage2 bootstrap of llvm/clang/compiler-rt/clang-tools-extra should get triaged. At r241513, a three stage bootstrap with comparision of stage2/stage3 files completed fine. However at r241594 we now have the new regression reported in https://llvm.org/bugs/show_bug.cgi?id=24054...
