Here's my minimal test case. Compile with "-O3 -Wall -c":
#include
void frob(int *pi);
int main(void)
{
int i;
printf("i = %d\n", i);
frob(&i);
return 0;
}
No warning from 4.0.3 nor 4.1.2

Can I bribe you to work on it by fixing a Wine bug in exchange? :)

An even simpler test case of this bug (tested with gcc 3.4.5):
int main( void ) {
int rc;
return rc;
*&rc = 0;
}
> gcc -O -Wall program.c
(more stunning silence)

Simplifying things a bit:
void foo(int*);
void bar(void) { int x; if(x) foo(&x); }
gcc -c foo.c -Wall -O2 -Wuninitialized
(More stunning silence.)
