Well, the problem is not in compare. It's even earlier. The program
just doesn't seem to be able to load the first element of data_items
into the eax register and then move it to ebx, but it works fine if it
loads it directly into ebx...

At this point, my %ebx has the value 0...

At this point, I haven't tried to run a debugger yet on the resulting
code to see exactly where the problem is, but the code looks so simple
that... Well, I'll try to figure out how to debug.

Thanks,
