   And the question is:   
      
   Embedded systems.  Address 0x00000000 is mapped to the flash.   
   I want to assign a pointer to 0x00000000 and dereference it to   
   read the first word.   
   That's UB.   
      
   How do I?   
      
   Now I guess that an embedded compiler targeting that certain   
   architecture where dereferencing 0 makes sense will not treat   
   it as UB.  But it is for sure a weird corner case.
