Yes: turn off optimizations ;-) isupper is just a table look-up so the 
compiler will optimize it. 
Also if you insist using -On use -gstabs3 or even -gstabs+ because they 
add some information about optimized variables, but even with that some 
variables stored in register can't be debugged and you'll need to move them 
to static variables
