            Bug ID: 30440
           Summary: crash on valid c++ code on x86_64-linux-gnu with
                    -std=c++14 (void
                    {anonymous}::CXXNameMangler::mangleFunctionParam(const
                    clang::ParmVarDecl*): Assertion `parmDepth <
                    FunctionTypeDepth.getDepth()' failed.)
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangb...@nondot.org
          Reporter: chengnian...@gmail.com
                CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
    Classification: Unclassified

This should be a recent regress. clang-3.8 does not crash.
