OK, thanks for looking into it. Warnings for ObjCMessageExpr can probably be
implemented in a separate patch.
It looks like clang still doesn't issue overflow warnings when the called
functions have a void return. Should we try to fix it in this patch too?
void foo(int);
void test0() {
foo(4068 * 1024 * 1024); // no warnings
}
