3. How could you prevent this outcome without changing the code?

compile with -Dii="a = 1, b"


It's still undefined behavior, and can do whatever it wants. 

Then how about this:
compile with -D"strcpy(a,b)"="ii"

PS
I would have suggested this: -D"strcpy(a,b)"="strncpy((a),(b),sizeof(b))"
but that give problems with string.h, which can be avoided by doing the following:
touch string.h
touch stdio.h
gcc -nostdinc -isystem . -D"strcpy(a,b)"="strncpy((a),(b),sizeof(a))" \
-save-temps -o test test.c
but this is way to compiler and OS specific for the clc newsgroup :-)

Kind regards,
