           Summary: ++ postfix operator increments too soon
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: bmead15@cox.net
                CC: gcc-bugs@gcc.gnu.org
  GCC host triplet: I am sorry I don't know what goes in here

With the following line of code:
*s++ = toupper(*s);
The 3.2.2 gcc increments s before the value is determined on the right side of
the equal sign.  So what happens is *s gets the value of toupper(*s+1) not
toupper(*s)
The bug did not occur in version 3.1.1 of gcc.  I have not run tests on versions
in-between these versions.  The gcc version 3.2.2 is the standard one that is
included in the Mandrake Linux 9.1 distribution.  If a known fix for this is
possible by recompiling gcc 3.2.2 or upgrading to a newer gcc please let me know.
