           Summary: wrong calling of functions in certain circumstances (see
                    the sample code)
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: l_belev at yahoo dot com
                CC: gcc-bugs at gcc dot gnu dot org

/*
 * this sample should print AbCdEf and does it
 * when it's compiled with -O0 or -O3, but when
 * it's compiled with -O1 or -O2, it incorrectly
 * prints ABCDEF. I looked at the generated assembler
 * code, and obviously it's erroneous.
 * (the external func putchar does not interfere with
 * this gcc bug - without it the generated code is bad too)

int lower(int x) { return x + 'a'; }
