           Summary: Able to use a variable before it is defined
           Product: gcc
           Version: 3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: erickt at andrew dot cmu dot edu
                CC: gcc-bugs at gcc dot gnu dot org

int main ()
{
     int i = i + 5;

     return 0;
}

compiles with:
gcc -Wall foo.c -o foo;

Is valid code. This appears to work with any variable.
I think there should be a warning, or compile error to prevent this from occuring.

------- Additional Comments From pinskia at gcc dot gnu dot org  2003-10-16 21:46 -------
This is a already fixed on the mainline by warning that the variable is uninitialized.
This is a dup of bug 10538.

*** This bug has been marked as a duplicate of 10538 ***
