So if I understand you correctly, in acid main:ca is the equivalent to
char ** in C? And furthermore that the \s expression operates on acid
addresses rather than normal char * in C? From trying things out in
acid a little bit, it seems like this is the case, but I'm not
positive.

I see what you're saying about cp not being initialized, but I
compiled with the -N option and I assumed that this would rectify the
situation of things being optimized away.  Interestingly enough if I
do **main:cp\c in acid it gives me 'W', but *(main:cp\s) gives me
garbage, whereas *(main:ca\s) gives me "Hello".

Thanks for the response, any other help would be appreciated!
