ExceptionHeader

A D exception object consists of a header, which is a wrapper around an unwind object header with additional D specific information, prefixed by the exception object itself.

struct ExceptionHeader {

static if(Throwable.alignof < _Unwind_Exception.alignof)

ubyte[_Unwind_Exception.alignof - Throwable.alignof] pad;

Throwable object;

_Unwind_Exception unwindHeader;

static if(!(GNU_ARM_EABI_Unwinder))
