While the x86 CPUs allow access to memory objects to be unaligned it happens that most of the modern designs require objects to be aligned - or they will fail with a buserror. That mode is quite known by big-endian machines (sparc, etc) however the alpha cpu is little- endian.
The following function will test for aligned access to be required and set a config.h define HAVE_ALIGNED_ACCESS_REQUIRED (name derived by standard usage). Structures loaded from a file (or mmapped to memory) should be accessed per-byte in that case to avoid segfault type errors.
