EVALUATION A SIGSEGV happens in a method handle stub ad is used to trigger a NPE but because, the method handle stubs are called from the interpreter (or through a c2i), when the thread executes the throw_NullPointerException_at_call_entry, the stack is not properly aligned. Aligning the stack before the call in throw_NullPointerException_at_call_entry fixes the problem.
