Description tkhai 2013-09-05 11:42:32 UTC

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: http://gcc.gnu.org/ml/gcc/2013-09/msg00033.html

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