--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The wording is also quite confusing - it should probably say
'dereferencing 'p' would access uninitialized memory'.

void bar (const void *);
void *foo(int sz) {
    void *p = malloc(sz);
    bar(p);

    return p;
}

is diagnosed as well.  We have duplicates about this - it is a deliberate
choice to diagnose here given the function signature suggests it isn't
an initialization function.

Confirmed, but duplicated of PRxxx
