Re: Bounds error in util.cpp

Hi Alexander,

I guess you meant this part:

    if ((csp==0 && (i==0 || !isId(constScope[i-1])) || (csp>0 && csp<6)) &&
        c==constScope[csp]
       ) csp++; else csp=0;

After a closer look it turns out to be wrong indeed. This was what was
intended:

    if (csp<6 && c==constScope[csp] && // character matches substring
"const"
         (csp>0 ||                     // if it is the first character
          i==0  ||                     // the previous may not be a digit
          !isId(s.at(i-1))
         )
       )
      csp++;
    else // reset counter
      csp=0;

Thanks for reporting this, I'll fix it in the next CVS update.
If you find more of these please report them.
Seems like a very useful tool you are working on ;-)

Regards,
   Dimitri
