           Summary: [-Wall] No warning when uninitialized integer
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED

Hi,

the following example compiles without warnings:

$ cat a.c
int func (int p)
{
        int x;
        if (p != 0)
                x = 1;
        return x;
}

$ gcc -c a.c -Wall
(no messages)

According to Ian Lance Taylor, this is a BUG:

My gcc version is 4.4.5. I can't try newer versions.
