[Bug middle-end/27825] New: False warning "value computed is not used"

["ebermann at decomsys dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following code generates warning "value computed is not used" which
I interpret as a gcc bug.

typedef unsigned char uint8;
uint8 arr[10];

void testfunc(void);

void testfunc(void)
{
    uint8 val = 5;

    (1 == 0) ? : (arr[2] = val); /* this line generates false warning */
}

Changing statement "arr[2] = val" with e.g. "arr[2] = 4" makes the warning go
away.
