Ask questionsAssertion failure with `lift-assignment-expr`

For the following file:

template <typename a> auto b() -> decltype(1(a())) {}

and arguments:

clang_delta --transformation=lift-assignment-expr --counter=1 unit.cpp

clang_delta crashes as follows:

clang_delta: /usr/include/llvm/Support/Casting.h:104: static bool llvm::isa_impl_cl<To, const From*>::doit(const From*) [with To = clang::AttributedStmt; From = clang::Stmt]: Assertion `Val && "isa<> used on a null pointer"' failed.
