well, you could
1) compile without optimizations and see if the code works (or at least 
"does not work in an expected way")
2) reading the example posted above, we see gcc producing a warning , it 
would be nice to get one too


the code was buggy, now it is better. Though, again, at a first glance 
the "-1" condition should always have caught, I fear we have here one 
bug showing another...

So I ask
1) without optimizations, does it work for you (as it used to work for 
us and continues to work)
2) with the fix and with optimiziation, do parentheses actually 
highligh/unhighlight (both of them). Try () [] and {}. Try checking that 
with parentheses close together, but also with some far-apart, like {} 
of a block several lines apart
