Hi Dan,
this is just a shot in the dark and most likely I will miss the
target...but...
Off what kind of memory you are running this code?
Das "cryot()" returns a pointer to newly acquired memory?
May be this memory is not RAM but flash/EEPROM?
If crypt() expects already allocated memory at the
pointers adress this may work on a PC because its
short and the stack is relatively large and you hit
nothing ... so it runs accidentally (so to say) and
fails on a Raspi...
Only some random thoughts...
Good luck!
Best regards,
Meino
