Summary: uninitialized use not spotted in "T x = x;"
Product: gcc
Version: 3.3.1
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: simon dot marshall at misys dot com
CC: gcc-bugs at gcc dot gnu dot org
With the program:
#include <stdio.h>
int main ()
{
int x = x;
printf ("x=%d\n", x);
return 0;
}
gcc -O -W -Wall does not report the use of x before initialisation (as it would
at the printf() if it had been "int x;").
Obscure I know, but we had a C++ code typo of this form which gcc should have
spotted.

This is already fixed in mainline, which gives
tmp/g> ../build-gcc/gcc-install/bin/gcc -Winit-self -c x.c -O -W -Wall
x.c: In function `main':
x.c:4: warning: 'x' might be used uninitialized in this function
