The 68K could not use an odd number as an address of data or instruction. Encountering an odd numbered address was an instant Guru Meditation.
For data 68000 and 68010 only. 68020 and up handle odd pointers just fine (albeit a bit slowly). Obviously branch (jsr, jmp, rts, rte and so on) to odd pointers would crash as usual.
While Enforcer is quite nice I would give my left kidney for
valgrind.
