             Bug #: 12061
           Summary: Assertion failed: ((!Initializer ||
                    isa<ImplicitValueInitExpr>(Initializer) ||
                    isa<CXXConstructExpr>(Initializer)) && "Initializer
                    expression that cannot have been implicitly created.")

delta-reduced example

Attached is a delta-reduced example that crashes clang with an assertion
failure:

Assertion failed: ((!Initializer || isa<ImplicitValueInitExpr>(Initializer) ||
isa<CXXConstructExpr>(Initializer)) && "Initializer expression that cannot have
been implicitly created."), function BuildCXXNew, file
/Users/kremenek/llvm/tools/clang/lib/Sema/SemaExprCXX.cpp, line 1023.

While this is invalid code, this assertion failure occurred on the original
example which was well-formed.

I believe this is a potential regression related to the generalized
initializers work.

To reproduce:

% clang -fsyntax-only reduced.ii
