Greg,
Thanks, I had noticed when the compiler optimized the program that a
couple of messages refering to:
Warning 304 in idea.c line 208: dead assignment eliminated "Z"
Warning 304 in idea.c line 453: dead assignment eliminated "<indirect>"
Since the code around line 453 is dealing with erasing the key used to
encrypt and decrypt the message after everything is done, I am assuming
that the problem is with the "Z". Since this is in the actual encrypting
function, I don't know if I can change anything and have the function work
with messages encrypted on another computer.
On an unrelated question. Why would the compiler compile a jump to 0x04?
I compiled another program that crashed my machine repeatedly and I tried
to use the debugger on it. I tried to compile using full debug, but I
only get the assembly listing without the C source that is supposed to be
there. Anyway, since I don't know that much about assembler or MC680x0
opcodes, I have tried to figure out what is wrong. It still beats me.

Haven't you ever seen the t-shirts with the "I survived … " or "Member
GeoPhysical year 19??" ? Note the dates and the order they are in. 😎
